The Decayed Original theory of Liu Ha is a 84 years old piece made by Liu Ha, a scientist living in Nanjing.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with asian patterns and some symbols pertaining to Buddhism.
This piece doesn't exist, but as a legend. It is said that in the year 2017, Liu Ha, the owner, made use of it in Nanjing to empower the Ha family. Now it is lost, or broken, we will never know.
