Ms. Wang Biyu was a retired worker from the Duyun City Food Company in Guizhou Province. After she attended Teacher Li's lectures in Guizhou in August 1993, she began the practice of Falun Gong. Soon her illnesses all went away. Since the persecution of Falun Gong began in July 1999, she had remained firm in her belief in Falun Gong. As a result, she was interrogated, arrested, and detained by local police on many occasions.

On the night of November 29, 1999, the local police broke into the homes of Wang Biyu, Yi Songhua, Liang Zhengfeng, and Zhou Yu and ransacked them. The police took away their Dafa books and personal property, and arrested these practitioners. At the police station, the practitioners were interrogated for 24 hours, nonstop. The police forced them to sign a "monitored residence agreement" (which stated that they must report to the police and get approval whenever they wanted to go out of town; otherwise they would be considered criminals on the run and could be arrested) before releasing them. Even after Wang Biyu returned home, the police often came to harass and threaten her and her family. As a result, her old illnesses recurred. She passed away on July 7, 2000, at the age of 64.
