In vernacular Chinese, futures are sales contracts, which are traded in the form of about one tenth of the margin. You can buy and sell indefinitely on the same day, and you can go short and long.

Option is a transaction of buying and selling stocks or commodities at an agreed time and at an agreed price, which is not available in China. Buying an option means paying an option fee, so you have the right to watch a movie if you want to buy a movie ticket.
