Recently, many people are discussing Duan Yongping's interview with Xueqiu. In the video, the most he says is 'I don't know.' Many people online ask stock analysts about stocks. No matter what they ask, the analysts can talk endlessly, as if they know everything. But the real investment tycoons are precisely those who often say they don't know. There are many things we don't know; excluding the majority of what we don't know, just a few things that we do know are enough. Investment is not about doing all kinds of varieties; it's not necessary to seize every opportunity. Focus on the few things you know well, and the money earned is already quite a bit. #Allindoge
