Uber lingkup already there.
Grab is for southeast Asia country only.

definitely not in China.
yes in other country where Uber is still alive.

That's in April. In August, Uber sold their China operations to Didi. It was in the news.

Didi Dache

China's version of Uber.

Uber ceased operation on early December and become uber didi something like that

Program only in Chinese coz only new takeover

U can take their taxi, their taxi strictly uses meter
Don't take taxi without driver info display on dashboard, those are cari makan

If u are in tourist area, those cari makan will be infested there, just walk abit further to get others taxi

Don't ask how much, then they will give u a price instead off using meter knowing you are not local

Yeah one more thing
Uber didi only works with Union pay, alipay and wechat pay

Msia credit card/master visa won't work there for now

You can use wechat there to hail for taxi.

Chinese wechat are more advance than us. But make sure you have local credit card and +86 phone number
