To make a firm offer in Hong Kong, you need a Hong Kong bank card, personal ID card and proof of personal address. You need a deposit of 6.5438 million, and you can trade the first-hand Hang Seng Index. The handling fee is about 30 Hong Kong dollars. Anything too high is a big scam.

You can also open a fund-raising account in China, and you can operate it for 5000 yuan. The handling fee is about HK$ 50-HK$ 60 bilaterally. If it is too high, the middleman is fooling you, and his cost price is generally within 40 Hong Kong dollars.
