Who was the second mummy in the Peng incident?

The place where the mummy of Lop Nur is suspected to be "Peng" is very close to the place where it disappeared.

Dong Zhibao, a researcher at the Institute of Environment and Engineering in Cold and Arid Regions, Chinese Academy of Sciences, found the mummy near Peng's missing place this time. When he was on a field trip there last winter, he found the mummy in a remote shawo.

Yu Chunshun has found out, and the last answer was wrong. Sorry!
