I met a girl who just came to our unit and she said she was a student from a Chinese medicine school and was about to graduate and wanted to do research outside. She said she was introduced by the police station and used an instrument to give us massage and acupuncture in the office every day. Later, it aroused our interest and asked us if we should buy this kind of instrument. He said that he could help us get it at school. I didn't buy it because I felt something was wrong. Now he is forcing me to buy that instrument. Then he asked us to introduce him to the next place, which is probably a new round of sales tactics
