famous leaders of student affairs in Colleges and universities who teach us the ideological and political work in typical colleges and universities
there is an introction about the student work of the key universities of the Ministry of ecation
there is an outstanding representative of counselors working in the front line like us, the national excellent assistant director Li Qin
the training course enables us to receive all-round training in all aspects< During the training period,
we also participated in two forums and two visits to Northeast Normal University, which enhanced our communication and knowledge< Through the training, I have the following experiences, which are reported as follows:
first, I fully realized the importance of counselors' work, understood the relevant background and policies of the state in the ideological and political work in Colleges and universities, and was encouraged
Xu Yanguo, director of the ideological and Political Work Department of the Ministry of ecation, pointed out in the training, The team of counselors is the personal guard of the party and the state, and the task of counselors is to train qualified socialist builders and reliable successors<
"it's easy to get a good teacher,
it's hard to get a good teacher"
,
this sentence puts the role of counselors in the work of ecating people in a lofty position,
as a counselor, we should not only teach students to survive,
but also teach students to be human beings,
it's extremely noble to be a tutor and good teacher< As a teacher who has direct contact with students' study and life,
counselors' speech and behavior not only affect the formation of students' Outlook on life,
world outlook,
values,
but also affect the growth of students< Therefore,
college counselors must fully understand their responsibilities,
further enhance their sense of honor,
sense of responsibility and historical mission,

the Ministry of ecation formulated the
regulations on the construction of college counselors on May 20, 2006, which put forward the orientation of college counselors. College counselors are both teachers and administrators, organizers, implementers and instructors of students' daily ideological and political ecation,
they are intimate friends and life mentors for the healthy growth of college students< According to the regulations, counselors should account for a certain proportion in the evaluation and employment of university teachers, the evaluation criteria should be independent, the evaluation criteria should be in line with the actual work of counselors, and the achievement identification should be flexible< Director Xu pointed out that in the future, the Ministry of ecation should organize regular training for counselors in combination with the improvement of their comprehensive quality, and organize the selection of national excellent counselors, so as to create a good platform and environment for the growth of counselors< In combination with the Ministry of ecation '

orders, director Xu showed us the importance, background and future development of counselors' work.

feel much more drum
dance, more energetic< Second, we should fully realize that we should improve our ability and quality to adapt to the student work in the new period. How to meet these new expectations and requirements and solve the problems existing in the current
student work is a problem that must be faced up to and urgently needed to be solved in order to do a good job of College Counselors in the new period< Through the explanation and teaching of relevant leaders and experts in the training process,
I deeply realize that the counselors in the new period are not the former nanny counselors,
fire brigade counselors and management counselors<
contemporary counselors should understand the importance of their work,
deeply understand and master the knowledge of mental health,
be familiar with the characteristics of the working group,
implement the party's major policies into the student work,
be an expert counselor,
only in this way can
have the ecational effect on students. After listening to the reports of experts, I deeply realize that
I have many shortcomings in student work
these deficiencies include,
insufficient cognition of students,
insufficient level and structure of self-knowledge,
insufficient ability to solve students' psychological problems,
insufficient ability to keep pace with the times and do a good job in students' work,
insufficient theoretical literacy. In the future work, we must face up to these shortcomings,
be determined, planned and step-by-step to supplement and improve, make up for the deficiencies, improve their ability and quality,
strive to be a qualified college counselor,
adapt to the needs of the post,
meet the new requirements and expectations of the majority of students in the new period and new stage
three, fully aware of the advanced nature of the instructor's model, and realize that there is a big gap between
training course. We invite the national excellent counsellor and the national excellent student Huang Lai daughter's counsellor
ring the training, experts have repeatedly mentioned the last national excellent counselors
Fudan University "forgive me", and I was deeply impressed by the touching deeds of the two excellent counselors<
1
, to be a conscientious person
"words of inclusion" is the epitome of the work of an ordinary college counselor, her behavior is very ordinary,
very ordinary,
it can be said that as long as a counselor who has been with students for four years, she will experience the trivial work of inclusion,
as long as she has a little sympathy and a little sense of responsibility
responsible teachers will sincerely pay for the students,
every senior
school counselor has a certain writing ability at the same time,
but why is there only one
inclusive heart language
only one inclusion? It shows that we are not living with our heart,
working with our heart
of course,
we can say that there are too many
trivial tasks that make us have no time,
especially when there are large-scale activities or important periods,
we don't even have time to sleep,
but we can't do it every day, every week, every month,
including diary,
I believe she doesn't have so much time to write diary,
what she wrote was weekly notes
this shows that inclusion is a person who has a heart of
and a heart of
life, he will certainly have a heart of work,
in order to serve the students well in his work,
lead the way<
2
, be a person without regret and selfless dedication
Li Qin put forward his theory of paratroopers in his report: if a person asks a paratrooper, you may be surrounded and arrested by the enemy as soon as you fly,
aren't you afraid? The paratrooper replied:
we paratroopers were born surrounded
- we want to be people who have no regrets,
we want to be people who give selflessly
I think it's very vivid and appropriate for counselors to
talk,
we should agree< The story of Li Qin and his classmates helping Huang Lainu and his father selflessly in his report has infected everyone,
this kind of help has surpassed the level of teachers and students,
and even the level of relatives, which shows that he has fully understood and applied the theory of paratroopers to his work practice.

legal. virtual currency mining to make money, digital currency hoarding to make money, virtual currency speculation to make money, digital currency move bricks arbitrage to make money, open a digital currency trading platform, charge fees are good ways to make money 1, virtual currency mining to make money : This is the most original way to make money with virtual currency. Through the purchase, rent, or self-assembly of mining machine, installation and operation of specific mining program software, 24 hours a day continuously running mining. The earlier the project, the more opportunities there are for mining, and the greater the harvest. For example, bitcoin, now the cost of mining is higher and higher, but the bitcoin is less and less. Therefore, the best way is to find projects that contribute to the development of world blockchain in advance, and get involved in mining as soon as possible to obtain early dividends. Then hoard the money and wait for the later appreciation before selling it 4, digital currency move brick arbitrage to make money : in the field of digital currency, there is a way to make money without losing money, that is move brick arbitrage. The digital currency transaction led by bitcoin is a pure market behavior, which is not regulated by the financial system of any country or region. The digital asset itself is encrypted, but it is multi-party proof, at the same time, it is completely transparent, and anyone can query it 5, open a digital currency trading platform and charge a handling fee . These are basically the profit models of mainstream digital currencies such as bitcoin, Ruitai coin and Laite coin. Virtual currency investment is risky, and there is no limit on the rise and fall of stocks in virtual currency, so it needs to be cautious to invest in virtual currency. At present, Ruitai coin, Weimeng coin and Ethereum perform well in the market

As a proct of e-commerce, virtual currency is playing a more and more important role, and it is more and more connected with the real world. However, with the growth of virtual currency, the relevant laws and regulations are lagging behind, which has laid many hidden dangers

with the continuous progress of technology, electronic payment (including electronic money) is changing people's payment habits, but also changing people's consumption habits, promoting the expansion of consumer credit. It is necessary to pay close attention to the innovation of the form, the evolution of the nature, the difference of the operation mode and the possible impact on the credit risk and moral hazard of this new thing, and properly supervise it. But the more important thing is to give the market main body corresponding development space, avoid strangling the development vitality of the corresponding business organization in the early stage of market development. Therefore, the best way to treat e-money is to observe its changes and strengthen research. In the face of such remarks as "q-coin impacts the RMB financial market", we need to discuss them in the context of scientific and technological progress. The key to understand the problem is how to design relevant policies and encourage the development of electronic payment instruments such as electronic money, rather than the harm of speculative virtual money and electronic money. We call for strengthening supervision

6. Digital currency
unlike virtual currency, digital currency is neither bitcoin nor q-coin! That is to say, it is different from virtual currencies such as bitcoin and Ethernet
virtual currency can only be closed in circulation on the network, just like Tencent's q-coin and Huixin cloud software collaborative instry ecological chain platform, they can only be used for their own procts. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency, bitcoin is illegal digital currency. As for legal digital currency, there is no unified international definition. Yao Qian, deputy director of the science and Technology Department of the people's Bank of China and head of the preparatory group of the digital currency Research Institute, believes that the digital currency researched and issued by the people's Bank of China is indexed RMB. From the perspective of national schemes, it belongs to legal encrypted digital currency, which is not only a payment tool but also a currency. Correspondingly, virtual currency is also called illegal fixed digital currency. Li Lihui, head of the blockchain working group of China Internet Finance Association, once said that digital currency must have legal status, national sovereignty endorsement, and clear responsibility subject of issuance. Virtual currencies represented by bitcoin and ethereal currency have no country, no sovereign endorsement, no qualified issuers, and no national credit support. These are not digital currencies
digital money is not equivalent to virtual currency
since digital money can be used for commodity trading, is Alipay and WeChat payment a kind of digital currency?
Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. These are all payment methods based on electronic accounts, which are in essence just a process of informatization of legal currency, not digital currency in a strict sense. For example, the amount of Alipay or WeChat transactions is essentially banknotes on bank accounts, but it is electronic form. The "100 yuan" displayed on the mobile phone will correspond to the real 100 yuan in the bank.

7. Before the design of this coin recognizer, we used a lot of information about this aspect for reference, and decided to design a composite coin recognizer after research. This kind of recognizer has the advantages of simple structure, low cost, high recognition accuracy and can be widely used in various fields. Therefore, this kind of recognizer will occupy a large market, and there will be a lot of room for development
the principle of compound coin recognizer: the compound coin recognizer is mainly composed of plate capacitance sensor, inctance coil sensor, detection circuit and single chip microcomputer control circuit. The variable gap flat-panel capacitance sensor can identify the authenticity by checking the thickness of coins. When coins enter the flat-panel capacitance sensor through the slot, the capacitance of the sensor will change. The sensor can also detect the material of coins, but this is only an additional function. The change of capacitance is converted into voltage signal by AC bridge equipped with capacitance sensor, and then the signal is amplified into rectification circuit by amplifying circuit to change AC into DC. Then, the interference signal is filtered through the active low-pass circuit, and then input into the AD converter after passing through the voltage comparator to convert the analog signal into digital signal and send it to the single-chip microcomputer control circuit. You can identify counterfeit coins.
