Why are so many people so secretive?

Zhang does have his characteristics and advantages. He dares to say that he is also humorous and has great military knowledge. But it's not once or twice to talk about an unknown address or make jokes. You think too much about the war of public opinion. Professor Zhang is not that valuable.

For example, he was wrong to escort in the Gulf of Aden a few years ago, almost the opposite. His prediction of Gaddafi was completely wrong. There are also fishing boats against aircraft carriers, kelp against submarines, etc ... Malaysia Airlines even told a joke a few days ago, which was more than 700 degrees below zero.

Therefore, netizens simply call it the director of the strategic flicker bureau.

Professor Zhang's temperature is 700 degrees below zero.

There seems to be nothing wrong with the temperature above 700 degrees below zero, but why say a value without it? This is like saying that the average height of human beings is above 50CM.
