Because the stock trading system in Hong Kong is very backward. Although Hong Kong is an international financial center, the stock trading system is generally 5- 10 years behind the mainland, and many people still have to place orders by phone. Once there is power failure or communication signal problems, it will cause losses to investors.

In addition, in bad weather, it is difficult to guarantee the safety of securities practitioners and investors on their way to and from the exchange, so they simply close the market to prevent risks.

Throughout the world, Hong Kong stocks, Taiwan stocks and US stocks are closed due to abnormal weather, especially typhoons.

In contrast, only two blowouts prevented the normal trading of China A-shares, and I am also an A-share securities practitioner. I was the only one who left work early in history, and even the second time I went to work was less than 15 minutes.
