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.

If the handling fee is not settled, change the platform. There are many platforms now, so don't pass your blood vessels into his mouth.

The Hang Seng Index trades 20 times a day, which is a very common short-term trading. If the handling fee is too high (for example, 200 Hong Kong dollars for bilateral transactions, 20 times a day, the handling fee will be as high as 4,000, and the broker will earn you a commission of 3,200 Hong Kong dollars a day. I don't know if you can make money after a hard day's trading, but brokers will make a lot of money.
