Also known as Master Yun, he is the president and a professor at Beijing University, as well as a renowned writer in Country Z. He was the mentor of the late Jun Lao and Jun Yifeng, who perished in a fire a few years ago. Grief-stricken, he retreated to the Northeast countryside for several years before returning half a month ago. He owns a six-entrance, six-exit siheyuan that was formerly the residence of a prince, located next to the Forbidden City. He is deciding to sell the property due to uncooperative tenants.
