I have a Qing Dynasty jade bi of quite good quality, which I usually wear on my chest. Speaking of the origin of this jade bi, it can really be said that it was "bumped" into. It was an afternoon in the autumn of eighteen years ago. I happened to have something at home, so I asked for leave and went home early. On my way home, I had to pass through a fairly large open-air flower and bird market, where there were sellers of potted flowers, birds, and jade articles. I was walking with my head down at the edge of the market when I accidentally bumped into a young man in his twenties. Little did I know that this "bump" would bring me this emerald jade bi that has accompanied me for eighteen years.
