When Aang was brought to the Official Avatar Aang Fan Club, Hei-Won introduced him to Yee-Li, who promptly showed him the airbender flute she had bought from a traveling merchant. This immediately sparked the Avatar's interest, as his mentor, Monk Gyatso, had once owned such an instrument as well. Yee-Li asked if he knew how to play, whereupon Aang did just that. Delighted, the young girl began to dance to the music. Later on, she and her fellow club members enthusiastically said goodbye to the Avatar.
