Translation:My parents are Chinese but I do not speak Chinese.
Very common where I live in California. I am one myself. Maybe likewise for all other East Asians who have immigrated to America. And this is a big issue because our parents push us to be successful in a new country but sometimes the mother tongue falls by the wayside. There is big family pressure to learn our mother tongue when we cannot learn it automatically from the markets, the streets, and the schools.
I speak Japanese and Chinese but I'm very sceptical about a DL language that uses a non-latin alphabet. There is a Russian course in the incubator but Russian "only" uses a cyrillic alphabet which is not that hard to learn. Japanese and Chinese would take that problem into a whole new dimension.
Has traditional and simplified settings. As far as I know, only Mandarin. Very similar to Duolingo in interface, but not as interactive.
