The Decayed Bow of Wongsojoyo Echalotte is a 1109 years old piece made by Wongsojoyo Echalotte, a fletcher living in Beijing.
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 900, Wongsojoyo Echalotte, the owner, made use of it in Beijing to empower the Echalotte family. Now it is lost, or broken, we will never know.
