I especially appreciate several points. Speaking of appreciation, different people appreciate different things. Some people will appreciate it because of some people's opinions, and some people will appreciate it because of some beautiful works. The following are articles from several viewpoints that I particularly appreciate!

I especially appreciate 1 a passage from a friend yesterday. I don't know who said it, but I especially appreciate it:

1, the theory is extremely important. Without understanding theory, there is no thinking frame and logical system. All you can do is be confused or confused, and you will become a taxi driver.

2. Theory must be internalized in the heart and become the accomplishment and quality of researchers;

3. The study of theory should not be a "dazzling skill study", and the theory should be put into words. Theoretical articles are difficult and obscure, which is not worthy of recognition. This is the failure of researchers;

4, theoretical research can not be smuggled, can not try their best to raise because they are good at having a theory (method), and try their best to belittle the theory (method) that they are not good at;

Even asserted that "if you don't understand a certain theory (method), you can't get along." Such a strange idea, with bootleg goods, must be clarified and strongly criticized!

5. Theory (method) is a tool to solve problems, not a tool;

6, theory and history, the two should cooperate well, complement each other, do not understand history, no matter how many theories are in vain!

Let's talk about it from my own experience.

In retrospect, I often criticize "theorists", but what I like to ponder is "theory". Not long ago, I chatted with Director An and talked about "the difference between industry and Internet" and talked about the viewpoint of "different time constants".

Isn't this actually a kind of "theory"? I also complained that in Shanghai, few people can talk to me about such topics-in fact, friends in Shanghai generally don't like theory very much.

The above passage, 1 point attracted me. When we study theory, we actually want to get structured logic. Every time I have a meeting, write an article and do PPT, I often pay too much attention to theory.

I often feel that PPT is too long, and I hope to delete a few, but I always feel embarrassed. Why is it difficult? Because some contents have been deleted, you will feel that the theoretical logic is incomplete and flawed.

This way of thinking is actually a habit. I sometimes get angry with myself: there are many things worth doing, so why bother to think about them? I think the motivation behind it is that I don't like the feeling of groping in the fog, and I like the carefree feeling that "all other mountains look short in the sky". . This is probably my song with a 2.

For example, since I came into contact with the concept of big data, I feel that the popular views are very confusing. For example, I hate the definition of "4V". Big data is not used to show off IT skills, but to solve business problems. As mentioned in points 3 and 5 above.

To understand this problem in a structured way, I think repeatedly: What problem does big data solve? Later, I learned that the advantage of the era of big data lies in acquiring knowledge and promoting intelligence.

To say that this conclusion is not just "I think", but can be combined with my experience and experience in series data analysis for more than 20 years, combined with methodology.

However, when I turned to look at some successful cases in society, I suddenly felt that this understanding was one-sided. So I revised the "theory" to: the advantage of the era of big data lies in acquiring or carrying knowledge, thus promoting intelligence. This is consistent with points 5 and 6 above.

I went to a meeting in the city yesterday and suddenly found that this definition is very narrow. Because big data often records more complete information, it can be combined with existing knowledge to get new information.

Therefore, the above viewpoint needs to be revised as follows: the advantage of the era of big data lies in acquiring or carrying knowledge (or information), thus promoting intelligence.

The process of changing opinions is actually the process of constantly structuring opinions. This brings us back to the point 1.

The longer you engage in innovation, the more important it is to practice. Why? Because there are inevitably loopholes in the theory, it needs to be corrected by practice.

Moreover, China's long-term "emphasis on paper assessment" has led to too many short theorists (see points 2, 3 and 6).

The more empty theorists I meet, the more important it is to practice. This is probably why I like theory and hate it: what I hate is not theory, but empty theory.

This passage also prompted me to reflect: I have been criticizing the 4V theory, but is this theory wrong? Actually, that's right IT's just that this theory considers the problem from the perspective of IT rather than users.

This theory guides the work of IT personnel. What I object to is only the abuse and generalization of this theory, which misleads Party A .. This is the fourth point.

Back to the fifth point, the theory should be useful. In fact, the study of big data must focus on such a purpose: how to use big data to create value for enterprises? To this end, the theoretical answer is: What can big data do? What is the right thing to do? What is efficient?

What's the use of these problem theories? This is because: logical thinking is clear, there are fewer loopholes, and the risks in action are reduced.

Why do I like theory? There seems to be a reason: in the past 20 years, I have been engaged in relatively high-risk technological innovation.

Deep down, I hope that through theoretical thinking, I can think about the problem as early as possible to reduce the risks in my work. Why don't friends in Shanghai like to talk about theory?

Because Shanghai likes to do things fine, fine, and even to the extreme, instead of wandering in the new world, not advocating tossing and playing new tricks.

To put it bluntly: Shanghai is more like "middle-aged and elderly people" than "young people". Its soil is suitable for making brands, but it is not suitable for making advanced innovations. Every city has its own characteristics. There is nothing wrong with this feature of Shanghai.

I am especially grateful to 2 fans and friends who care about me. In order to answer the questions of several fans and cherish everyone's time, I will definitely get rid of verbosity and superfluous words today and discuss a few questions with you briefly. I hope to get your patience.

There are indeed many aspects that must be paid attention to when appreciating and collecting Jun porcelain. However, it depends on your choice tendency. At least the following, see how you choose.

The first is wood kiln, coal kiln and gas kiln. In the firing process, wood is used as fuel, which has low calorific value and slow temperature rise. Therefore, it takes a long time, resulting in low yield, despite painstaking efforts in glaze matching.

Taking coal as fuel, the calorific value of coal is high, generally above 7000 Dhaka, which not only solves the problem of slow temperature rise, but also releases various mineral elements and even a small part of smoke and dust in the coal when the glaze melts, which plays a role in adding fuel to the fire and icing on the cake.

Therefore, Jun porcelain produced in coal mines has a thick glaze, a dark color, a little bright and turbid, a strong sense of hierarchy, and the kiln change is beyond imagination, which may show the meaning of kiln change.

From these aspects, everyone will know the difference and preciousness. Jun porcelain fired by liquefied gas (natural gas) has the greatest advantages of controllable fire temperature, ideal temperature rise and ideal output. But the change of glaze kiln is different.

Followed by treasures, fine products, defective best (here I will elaborate on wood kiln, coal kiln and gas kiln one by one).

First, the treasures of Jun porcelain (including other artworks) are not limited to the appreciators, so it is different as a collection, because the price of rare works is quite high, which depends on the strength.

Secondly, there is a lot of knowledge about fine products, because in fine products, you can definitely find rare things. The reason is very simple, that is, when the kiln owner opened the kiln, he had eyes.

As an appreciation and collection of fine products, my opinion is to choose the most eye-catching one. For example, you pay attention to glaze color, or the shape of objects, or the uniqueness of glaze color.

Third, it is very important. I hope to help our friends here, that is, you should not underestimate the "defects" of Jun porcelain.

The so-called defective products are defective works. For Jun porcelain, it depends on your Bole vision.

My simple point of view is that the glazed kiln has become unique, unique and unique, paying special attention to its own vision, that is, it has one or even two defects, which is definitely not given to us by time or heaven at any time.

Some friends may ask, what are the selection criteria? My answer is: Choosing criteria is like eating in a hotel. You already know in advance what you want to eat, what tastes good and what tastes good.

Let's call it a day. Without your attention, I would get lost. So, I ask your attention, of course, if you like my point of view.
