The students have two plays （戏剧）: The Tortoise and the Crane (《龟与鹤》) and The Golden Hatchet (《金斧头》). Every student plays a character （扮演角色） in the two stories. Most students like it and they also have some problems （问题）.
Meng Qingyuan plays the tortoise. He has a problem with the neck of the tortoise. "You have to move the puppet's （皮偶的） neck softly or it will get stuck （卡住）, "he says.
