Who played Yan Yan all my life?

Yan Yan was a little girl all her life, played by a Stern submachine gun. At that time, when she played the little Stearns submachine gun, she was really domineering! No one is more proud than her cold and arrogant little eyes and the graceful steps of the model. But she is also a kind and lovely little girl, and she also has her own favorite games. So Yan Yan, a little girl's life, was played by Stena. joke
