Do high-speed trains in China have an area that can be used to make audio/video calls?

I read on this answer by iBug:

Speaking loudly or playing your media out loud (music / videos / TikTok etc.) is generally frowned upon in public places, particularly in closed areas like train cabins

Do high-speed trains in China have an area that can be used to make audio/video calls? E.g. in French TGV we’d use the bench next to the luggage storage space.
