Hack Chinese and Domino Chinese have partnered! All of Domino Chinese's lessons are available in Hack Chinese as pre-made lists. You can find your lessons and add them to your queue here: Domino Chinese in Hack Chinese.
If you came to Hack Chinese from a link in Domino, your onboarding questionnaire should have synchronized your Hack Chinese account with your Domino account. If this did not happen, send us an email and we'll get you sorted: firstname.lastname@example.org.
