Can Yongchuntang's stock really be listed?

Yongchuntang is a company listed on the OTC market in the United States. But now in the off-site market, it is equivalent to our domestic SME board, but it is a listed company that publicly discloses financial reports and information, so there are stocks, not to say that they are not listed, but the trading volume is small and the trading crowd is small, unlike the domestic A-share market, Hong Kong H-share market, American Nasdaq, NYSE and other main board markets, with high trading volume and active trading. However, in the next two years, the company will be listed on the main board of Nasdaq or NYSE.
