A joke about buying a house

A boss in Lu Yi promised San Xiao that he would buy a villa in Beijing 15 Ring Road. Xiao San's mind was set, and she was not at ease. She flew to Beijing to find out and took a ride to ask the taxi driver in Beijing, "Where is the 15 ring road in Beijing?" The driver replied, "The 7th and 8th Ring Roads are in Hebei, the 9th and 10 Ring Roads are in Henan, and the 15 Ring Roads are probably in Wangpima, Xinji, Luyi County, Henan Province. The woman shouted: I am his ancestor! And then fainted!
