You are Polly Chan. Your mom is teaching you how to make tong jyun over a video call because your Chinese isn't good enough to read the recipe she linked.
湯圓 [tong jyun] is a little chat about cooking & culture. Play as Polly Chan, a Chinese American whose only knowledge of Chinese comes from speaking with her mom at home and the Saturday school lessons she didn't really pay attention to. Help her make tong jyun to celebrate the lantern festival even though she doesn't even know how to write tong jyun in Chinese.
