  That’s for the entire S&P 500 index and only applies to a 20% drop. Chinese regulations apply to individual stocks and kick in at 10%. That’s a massive difference. And re the Limit Up-Limit Down rule, that’s a trading halt for five minutes, not the entire day. Again, not as much of a, but still a massive difference.
