A Chinese piano player who lives in the same apartment complex with Nodame and Chiaki in Paris. He tends to become very sentimental, especially when homesickness is mentioned. He attends a different conservatory than Nodame. In contrast to Chiaki and Nodame, he is driven to succeed by the expectations of his family. He has intense stage fright.
When Chiaki went on a world tour for 3 months, Yunlong and Nodame developed a good friendship which made Chiaki, on his return, uncomfortable and unwilling to meet Yunlong. After a mediocre performance at a piano competition Tanya also participated in, he reluctantly considers returning to China to become a piano teacher. He enjoys eating good food, particularly if Chiaki cooks or pays for it.
