We learned different levels of knowledge and discussed different things. Teacher Liu's personal view is the exploration of dream lovers themselves, and then the conclusion is like a simple science popularization. But when it comes to academic research, it is necessary to have a rigorous academic research attitude, give sufficient evidence and strict logical reasoning, and have enough professional knowledge to discuss it. We can't use a gene sequencing to discuss image processing algorithms one by one. Scholars in the Red Institute must have their own opinions, and everyone's knowledge reserve is different. They must have studied all the relevant materials repeatedly and criticized them with the attitude of academic research. Mr. Liu's research is a kind of personal research, which is grassroots and not necessarily rigorous. From the perspective of academic research, many ordinary people have not seen so much historical materials and knowledge, and it is easy to be preconceived.

For a simple example, some time ago there was a discussion about whether China should build a large quantum laboratory. Without so much knowledge, we can't communicate with experts, just follow the trend and make a fuss. Similar to the recent epidemic, many people even madly spray experts to send papers. The publication of the paper is the result of the hard work of experts, and it is necessary for experts to accelerate the research and development of vaccines and drugs. Many people are ordinary people who have not received professional education, and some general education is also a simple explanation. It takes years of study to communicate with experts. Just like you told your family about your major in college, you just explained it in a simple way, but your family still can't communicate with you smoothly. I don't think everyone can study redology academically, and not everyone can reach that height. In the words of a senior in Tsinghua, don't look, don't listen and don't say things you don't understand. I want to say that hobbies do not mean research. We just need to talk about the hobby of a dream of red mansions. When it comes to academic research, you'd better read your own papers and don't make a fuss.
