Recently, many people have been discussing Duan Yongping's interview on Xueqiu. In the video, the most frequent thing he says is "I don't know". Many people online ask stock analysts about stocks, no matter the question, the analysts can talk endlessly, as if they know everything. However, the real investment masters often say "I don't know" the most. We don't know many things; by eliminating most of the unknowns, the few things we do know are enough. Investing is not about doing all varieties; not every opportunity needs to be seized. Doing well with the few things we know can already earn us a lot. #Allindoge
