TikTok is a Cultural mirror, more so for the younger generation than older, but quite universal overall.
There are a lot of Non-English Memes that come from TikTok, and that means more avenues of Creativity for non-Western Countries, which is why Asians enjoy the visibility they attain from the platform, not to mention a means to gain fame and money.
Additionally, I've noticed from the WhatsApp Groups of professionals older than me, that most of their shared Memes are exported TikTok videos, especially from the Mainland; many of my professional peers are South East Asian Huaren so it is a way for them to connect with their Mainland Culture if they don't visit often.
