Short selling in Taiwan

I am interested in shorting the stock market. I’d prefer to short the US stock market, but since I’m in Taiwan that isn’t so easy, and I would be satisfied to short the market here in Taiwan. It might be possible to short the US stock market with a local brokerage account in Taiwan, but I’m not sure. I don’t want to short any stock in particular, but rather the entire index (ie Taiex, or US Dow, S&P, etc).

I know how to do that in the USA, but I don’t know if it can be done in Taiwan, nor do I know any brokers here. I’ve never owned stock in Taiwan, much less shorted any. Does anyone have experience, or at least some advice?

Thanks in advance,
