《幸运儿》(Mr. Wing) is a paperback Chinese comic by Jimmy Liao（几米）, first published in 2003.
A Brief Introduction:
(Mr. Wing) Chairman has been so lucky ever since he was a child. He has everything and the best of all. Chairman is witty and comes first in everything. He has never been disappointed. Chairman is handsome and capable, has graceful and open-minded parents, a beautiful virtuous wife and lovely children. Many people have worked hard to pursue their dreams, everything comes easy for Chairman. Everybody likes Chairman. Chairman is a person who makes people envy and jealous. What's more? One day, Chairman receives a miraculous gift — a pair of wings.
The little pair of wings grow bigger on Chairman's back, allowing him to fly. People cheer for him as he has realized the dream of mankind. But then, Chairman finds the wings getting out-of-control. They take him off the ground anywhere and everywhere, anytime and any day. Chairman finds it so frustrated and eventually he decides to cut them off. The wings object. They take the unconscious Chairman off the operation table and vanish through the window. Chairman's family have been looking for him everywhere, but in vain. As time goes by, people seem to have forgotten all about Mr. Wing.
Mr. Wing is a tragic story of being lucky. Is he really lucky? Would you consider yourself lucky if you have a pair of wings, which are out of your control?
