Hello,
I am very interested in your project. I live in China and have experience in doing this. I can help you:
1. Translate the language of your app into Chinese.
2. Apply for Software Copyright Certificate in China.
3. Upload your App to China local App Stores.
P.S. In China, we can access the apple store, but not google play. What you need to do is to publish the apps in our local android stores.
Welcome to contact me for more details.
Best regards,
George
