It seems that Song Xiaojun is not a Phoenix TV star, but a guest star, so it is normal not to go.

I appreciate Song more, which is more real and supported by data.

It's best to settle down once in a while. Military science actually covers a wide range. From economy to machinery manufacturing, people can't know everything. They often watch TV and have no time to accumulate. After a long time, they became the target of TV stations' attention. They always say things they don't know. After a long time, the reputation stinks, the mentality drifts, and the technology is gone, which is harmful and useless.
