Fang Huai had much to say.
There was also much he did not talk about.
Some things, like the content of military reforms, were not entirely admired by Division Commander Jin. There was a lot to copy from militarily advanced countries, and many theories with Chinese characteristics had already been proposed domestically. The awesomeness of the military reforms was not in the process of formulation but in the process of implementation.
The crucial aspect was to what extent the comprehensive national power could actually implement military reform.
As Division Commander Jin said, overcoming obstacles required money and technology to make it feasible.
However, it was Fang Huai's "imagination" that was more comprehensive and his grasp on the direction of future technology development that was well-founded. This was the part that most dazzled Division Commander Jin.
Some foreign weapon parameters Fang Huai talked about were known to him, but there were others he did not understand.
