How does MM HF platforms work in Hong Kong?

This question specifically is in regards to Greater China pods. A-Shares afaik still do not have any real capabilities for single name shorting. It also has the up/down limit of 10%. Even in Hong Kong exchange, large portion of the trading names do not have enough short liquidity for institutions. How do these pods that do Greater China strategy hedge? Is it just basically a long only strategy overlay with index/US-ETF shorts? What are the kind of risk metrics required for PMs running Great China strategy on these platforms? I would assume it has to be more lenient than their US peers due to the lack of liquidity/increased volatility? Thanks.
