The Pittsburg-based app was unavailable for download in China in August of last year due to the country's sweeping education cracking down. The company told local media that they received instructions to strengthen the app. The app came to China.

In the last few years, China has been closing regulatory loopholes. In order to maintain a healthy digital environment, strict content moderation is required of services that have a lot of data.

According to its official social media post this week, the app is free to use, teaches 41 languages and comes with gaming features. Cantonese, the language spoken by people in Hong Kong and Macau, as well as a significant population of the affluent Chinese province of Guangdong, will be taught.
