After the PK recording of a program ended between Asus's proxy lawyer and Zhou Chengyu, a mysterious man appeared at the recording scene. He claimed his surname was Zhang. In 2002, he had purchased a notebook computer from Zhou Chengyu's second-hand notebook computer sales company. In 2003, he joined Zhou Chengyu's company and became his employee.
Mr. Zhang said that when he worked for Zhou Chengyu, he knew that Zhou Chengyu used to destroy hardware and then request warranty service from the after-sales department to replace old hardware with new ones. He told the reporter that some people who sold second-hand notebooks would replace the good hardware in the notebook computers with faulty hardware, and then take them for repair. If successful, they would obtain a set of new hardware. When the reporter asked if it would be noticed since there were data codes on the hardware labels after replacement? "You can slowly peel off the label with a hair dryer, and then stick it on the faulty hardware."
