Let me try to answer your question, I hope it will help you!

There are two channels to subscribe for Huaxia Global Select Fund on the 27th: one is to log in to official website of Huaxia Fund Management Co., Ltd. (/index.html); The second is to subscribe for China Construction Bank, Industrial and Commercial Bank of China, Agricultural Bank, Bank of China, Bank of Communications, China Merchants Bank, Postal Savings Bank, Minsheng Bank and major brokers. (Note: the minimum online subscription fee is 50,000 yuan, and the minimum subscription fee for bank outlets is 1 10,000 yuan)

If you have purchased Huaxia Fund before, you will have a fund account number beginning with 03 1, so you can provide this fund account number beginning with 03 1 no matter which channel you subscribe for Huaxia Global Select Fund on the 27th. If you haven't bought Huaxia Fund before, you have to open an account first. After opening an account, you will have a capital account number beginning with 03 1

You said that you have a capital card of Zhang Jianshe Bank, which may be a debit card of China Construction Bank. One card is enough, and you don't need to apply for a new card.

I wonder if I made myself clear. I wish you a happy investment!
