I have setup bank acs in china whenever i go to china . but lost the 2 cards and acc no. it has been like 5 yrs , will try to reinstate the account when in china. when ever you visit china , try to register and verify your youku , alipay, wechat pay , your ah tiong music app on hp , cos once you back in SG you cant do anything.
