i feel your pain on this one. We had a similar struggle trying to expand into China with a platform that relied on real-time connections. It's a completely different beast over there.
First thing - worth checking whether your platform can even operate legally. china has incredibly strict internet and moderation rules, especially for anything like Omegle. Many apps never get past that hurdle.
On the growth side, you'd need to rethink everything. Chinese language support is just the start. you'd want fast local hosting or a CDN, definitely mobile-first design (WeChat mini-programs are huge), and promotion on local platforms - forget Western social or search. Strong moderation and verification systems are non-negotiable too.
So many global apps fail because they try to transplant their US/Europe playbook. It just doesn't work. You have to completely step into the user's world there
