OnePlus shop in Beijing

Hello, guys. I want to change the screen on my OnePlus phone in Beijing. I know that they have Chinese site so apparently they sell these phones in China. But in Baidu maps I cannot find Oneplus, I have tried 一加 as well, it only shows Oppo stores. Should I try to go to Oppo and ask if they can change the screen or are there ezclusive Oneplus stores?
