At present, there are many platforms to support fund purchase, such as fund companies, Tian Tian Fund, Alipay, WeChat, brokers and banks. These all have their own advantages and disadvantages.

It is more convenient for Alipay and WeChat to purchase funds. Alipay platform fees are lower, and the amount of WeChat funds is small. Fund companies can only buy the funds managed by the company. The number of funds purchased by Tian Tian Fund is complete, and the handling fee is relatively cheap. Brokers can buy on-site funds, while banks buy funds with relatively high fees and a small number.
