What does oral sex mean in English?

Playing the flute means playing the flute tube (a traditional Chinese musical instrument). From Historical Records Zhou Bo Family: "Bob weaves thin songs for a living and often gives oral sex to people at funerals." ?

Tang Bai Juyi's "Please warn that the parents are innocent": "Choose a horse that plays the flute, although it is not a real person; If you are a rich man, how can you collect illegitimate children indiscriminately? " Chen Ming Ruyuan's "Golden Lotus, Little Star": "I would like to play the flute, win the stage and ride the wind."

Han Fu and Xiao

The appearance of Xiao can be traced back to ancient times. Archaeology in China shows that bone rattles dating back more than 7,000 years have been found in unearthed cultural relics, which archaeologists call "bone whistle" (unearthed cultural relics in Hemudu, Zhejiang Province, now in Zhejiang Museum).

These bone whistles are made of the midlimb bones of birds. Ancient people took bone marrow from bones to form a hollow bone tube, and then punched holes in the tube wall. They are about 7 cm long, 6-8 mm in diameter, slightly arc-shaped, with two or three holes on the convex arc surface, which can blow out several sounds, thus forming a bone whistle.
