On a summer night in 1999, two middle-aged women in police uniform were clasping their hands together in Huilai hotel in the small southern city of xulai. Due to the same occupation, they were dressed almost the same: Blue Short Sleeve police uniform, black trousers, black shoes and short hair. But the woman on the left had her hair permed around her hair tip. Her thin figure and delicate face looked very mature. However, the prominent muscles and sharp eyes on the back of her hand let people know that this is definitely a woman who is not easy to be provoked; the woman on the right looks like a European woman from the body, from face to chest to buttocks are the lengthened version of the former.
