四度Ｃ -- Four Degrees C -- is the name of a musical group that my wife has joined these recent years. The band was founded five or six years ago by Ms. Bizhu Xie (my wife's former colleague) and three close friends of theirs who were so interested in music. [Maybe that is why it was named "Four Degrees C."] Now the number of the group members has increased to 12 persons, including three men. They regularly practice singing and/or playing such musical instruments as keyboards, guitars, drums, etc., on Wednesdays. And the female members, invited by my wife, came to our place (Wufeng) this morning. Look at the pictures below, and you'll know they really enjoyed hiking together here -- in a . . . way!
