It is free to cancel the account itself, but some securities companies may require that the account opening fee for the two shareholder cards in Shanghai and Shenzhen be reissued =40+50=90 yuan. If you don't use this account all the time, there won't be any extra charges. At most, because there is no transaction for three consecutive years and the balance of the fund account does not exceed 100 yuan, you will be regarded as a dormant account in another inventory. If you want to use a dormant account in the future, go to a securities company to activate it.
