The first specific recommendation is Yinzhengtong or Yinjitong through online banking. When it was opened, the threshold was very low and the procedures were simple. Just fill in the monthly subscription amount. The advantage is that the monthly subscription amount can be changed frequently. Under normal circumstances, if the account balance is insufficient for two consecutive months, the fixed-term quota will automatically stop. Please consult your local bank for details of the fund's fixed investment business.
I hope it helps you.
