It's different. There is a price difference between stock index futures and Shanghai and Shenzhen 300 index, but the Shanghai and Shenzhen 300 index and the stock index are relatively "spot". Therefore, the price of the stock index fluctuates on the basis of the Shanghai and Shenzhen 300. So you will see that the Shanghai and Shenzhen 300 Index is 2000 points, but the stock index is 2200 points.
