  Like the Mawangdui silk manuscripts, the Peking University text, now referred to as the “Beida Laozi,” is divided into two parts. They are titled “Laozi Classic, Part 1” (Laozi shang jing) and “Laozi Classic, Part 2” (Laozi xia jing). This indicates that not only the Laozi was divided into two parts during the Western Han period, but also it was accorded the status of a “classic” (jing), which may give some credence to the traditional claim that the Laozi achieved canonical status during the preceding reign of Emperor Jing (156–141 B.C.E.).
