It's widely believed in Western society due to the language barrier to access Chinese social media.
But it's not true , or only half true 30 years ago. I personally know 3 or 4 of my alumina abandoned their expertise of Optical Engineering to pursue Lawyer career 20 years ago and made big money.
Another example is one of celebrity law professor (not lawyer though) who recently got involved in a controversy because of Epstein file. He shut down his “weibo" (a Chinese Twitter ) account. He also made tons of money. https://en.wikipedia.org/wiki/Luo_Xiang
China moves very fast compare to the western society. Something true today might not be true 3 years later. Let alone half-truth 30 years ago.
