Han Xin in the context of "Commitment device"

Zhang Liang (c. 251 BC – 189 BC), courtesy name Zifang, was a Chinese military strategist and politician who lived in the early Western Han dynasty. He is also known as one of the "Three Heroes of the early Han dynasty" (漢初三傑), along with Han Xin (韓信) and Xiao He. Zhang Liang contributed greatly to the establishment of the Han dynasty. After his death, he was honoured with the posthumous title "Marquis Wencheng" by Emperor Qianshao. Zhang Liang is depicted in the Wu Shuang Pu (無雙譜, Table of Peerless Heroes) by Jin Guliang.

Xiao He (257 BC – 16 August 193 BC) was a Chinese calligrapher and politician of the early Western Han dynasty. He served Liu Bang (Emperor Gao), the founder of the Han dynasty, during the insurrection against the Qin dynasty, and fought on Liu's side in the Chu–Han Contention against Liu's rival, Xiang Yu. After the founding of the Han dynasty, Xiao He became the chancellor and held office until his death. For his contributions, he is also known as one of the "Three Heroes of the early Han dynasty" (漢初三傑), along with Han Xin and Zhang Liang.

Huai'an, formerly Huaiyin, is a prefecture-level city in central Jiangsu Province in Eastern China. As of 2020, the built-up area (metro) of its 3 central urban districts had 2,544,767 inhabitants and the prefecture-level city as a whole had 4,556,230 inhabitants, down from 4.8 million in 2010.

Long an important regional center, Huai'an lies on and is named for the Huai River, the historical boundary between Northern and Southern Chinese culture. Once much closer to the East China Sea, it now lies in the middle of Jianghuai, the vast alluvial plain created by silt from the Huai and from the Yellow River, which flowed nearby for centuries prior to the massive floods in the mid-19th century which returned it to its old course north of Shandong. Huai'an is known as the birthplace of Han Xin, a famed general who helped found the Han dynasty and overwhelm Xiang Yu in Chu-han contention; Wu Cheng'en (1500–1582), the Ming author of Journey to the West; and Zhou Enlai (1898–1976), a prominent and early Chinese Communist leader who served as premier of the PRC from 1949 until his death in 1976.
