There are six or seven choruses alone, of which the Ching Ching Chorus, which must be the largest, has more than100 regular members. They have been practicing at a fixed time every Saturday at Stanford University for thirteen years now. Ching Ching is often seen by outsiders as a place for singles to meet.
光是合唱團就有六、七個，其中規模最大的要算青青合唱團，固定成員有一百餘位，每星期六準時到史丹福大學練唱，十三年如一日。
