Chinese plum
"Han Shi" is written as "chess" and the word is "one". In The Book of Songs, there are three viewpoints: Zhao Nan Zhuo Meiyou, Xiao Ya April, and Cao Feng Cormorant Dove. (The word "Mei" in Chen Feng's tomb and Qin Feng's final south is Mao Chuan's word "Wu", but the word "South" is not a fruit tree. ) It can be inferred from the pile that there should be plum in Shang Dynasty.
