You don't know much about Chinese firms in the US. Hartcourt, HRCT, for example was a US domiciled firm incorporated in Utah that had several operations in China around 1998. In 1999 it traded as high at $20. It's out of business. Its CEO returned to Asia... quickly.
What about briefly red hot stocks like China.com around 2000. There were all sorts of Chinese stocks trading more than a decade ago. Some were listed on exchanges then. Virtually all are gone.
As for your stocks, anyone can see what you post on. Most have been disasters.
