This needs to consider which indexes you usually look at. If we mainly look at the Shanghai Stock Exchange Index and Shenzhen Stock Exchange Index, we can consider Jiashi CSI 300, Penghua CSI 300 and Huaxia CSI 300, which have a good replication effect on the trend of Shanghai and Shenzhen Stock Exchanges and are also the most similar. If you want to track the Shanghai Composite Index separately, you may wish to consider financing Shanghai180; If you only track Shenzhen Stock Exchange Index, recommend Shenzhen Stock Exchange 50ETF Index Fund.
