There is a flower shop in Shiqun Alley. Although it is not very lively, it is acceptable. Chai Nansong went there during the Qingming Festival and bought a bouquet of white chrysanthemums. The next day, there were more than one corpse buried behind the flower shop. Chai Nansong raised questions about the client Jian.
"What do you think about the body being sold behind your store?"
"I don't know them."
