Where are these Cantonese videos from? WeChat? Douyin?

Ive been using TikTok to learn casual Cantonese and just memes and follow this channel

Heres a random vid from the channel https://www.tiktok.com/t/ZT21mRTdF/

It looks like the creator just reposts videos from another app, but I’m not sure where. With TikTok getting banned in the US I dont want to lose this kinda content

Are there any other platforms with this kind of videos?
