The ritual and the concert. After Mei learns that her family's panda comes from the ancestor Sun Yee, Ming and the family plan a ritual at the red moon to seal the panda away. Mei, meanwhile, discovers that she can control the panda, and she and her friends make money with it to buy concert tickets for 4*Town. Ming's guilt, anger and humiliation come to a head when she appears at the concert as a giant panda herself.
The crisis. The ritual and the concert collide, and Mei's panda has to be dealt with in a way that is dangerous for her and her family. Mei, who started the story deceiving her mother, must choose between suppressing the panda for her family's sake and keeping it for herself.
The resolution. Mei enters Ming's inner world and sees the young Ming's anger and her struggle to be good enough for her own mother. The two reconcile, and Mei chooses to keep her panda. The ending shows each of the Lee women accepting her own panda, and the family finding a way to live with it, as in the family's decision to keep the panda and reconnect with the temple.
Hidden meaning. Ming's behavior makes sense as inherited fear: her protectiveness is the same perfectionism she fights in herself, and the film's final image of acceptance is the family choosing messiness over repression.
