In his spare time, Liu Wenrui, a seventh-generation inheritor of the Qiyuan Village Dragon Drum, arrives at the village square on time to gather the team for practice. Most of the team members are local ecological forest rangers. On weekdays, they patrol the mountains, clear weeds and protect the forests; in their spare time, they memorize drum scores and practice drumming. To them, their hometown has been changing rapidly, but their commitment to guarding and passing down the century-old dragon drum tradition has never wavered.
