Hi,
I have rich experience uploading Android apps to Chinese app stores. I have active accounts in the first 10 app stores you listed. I've completed many jobs about uploading Android apps.
It's not really necessary to upload to so many stores. My proposal is to pick the largest 4 or 5 of them and upload your app. The top 5 app store cover about 90% of Chinese Android users. My bid is $30 per store.
I can let you know more insights with these stores. I have summarized some detailed statistics about the first 10 app stores in an Excel. Please contact me via PM.
