What does the traditional outing to the Chinese restaurant symbolize to the "newbies" on the Defenders track team?

The eating of the Chinese food among Coach and the new athletes symbolizes unity and acceptance. It is eaten by Ghost, Coach, Sunny, Lu, and Patty when Coach brings the newbies out for a tradition dinner designed to help the team bond and accept each other. Over this meal Ghost and the others reveal their diverse paths in life which have led them all to run track. Because of this, they recognize each other as being very much human and in need of respect and support.
