I tried. It seems that the limit for ICBC credit card to recharge Alipay is 1000. You can apply for installment for a single payment of more than 600, and each recharge must be staged separately. When recharging, you will be prompted to ask whether it is full payment or installment payment. If you don't choose installment at this time, you can apply for installment by phone or online banking the next day, but you must also apply separately for each recharge and will not merge.
