In the seventeenth year of Hongwu, when Xu Da was in Beiping, he got carbuncle on his back, and soon he got better. When Zhu Yuanzhang heard about it, he specially sent Xu Da's eldest son, Xu Huizu, to bring a letter of condolence and returned to Nanking with Xu Da in October. However, on February 27th, the 18th year of Hongwu, Xu Da was seriously ill and later died in Nanjing at the age of 54. After Xu Da's death, Zhu Yuanzhang announced his retirement from the DPRK, expressing his grief to the ministers and lamenting: "How can heaven take away my elite soldiers!"

Later, Zhu Yuanzhang went to his home to attend the funeral to show his grief; Posthumous title Zhongshan Wang, posthumous title "Wuning", was buried in the shadow of Zhongshan. Zhu Yuanzhang also personally wrote a tombstone for Xu Da (later called "Tombstone of King Xu Wuning, Emperor of Zhongshan"), and later allowed Xu Da to share the ancestral temple.

In September of the 23rd year of Hongwu, Zhu Yuanzhang gave his family three kings of Zhongshan to commemorate Xu Da and other founding heroes. In the third year of Yongle, due to Xu Da's "first virtue", officials of Taichang Temple went to Dagefang Temple to offer sacrifices to Xu Da every year in Zheng Dan, Qingming, the Central Plains, Mengdong and the winter solstice, so as to avoid imprisonment. Xu Da and Liu Ji became the first heroes to worship the ancestral temple in the Ming Dynasty, located in the East Temple.

Xu Da related introduction:

Xu Da was born in Zhongli, Haozhou (now northeast of Fengyang, Anhui). A famous soldier in the late Yuan Dynasty and early Ming Dynasty, the founding father of the Ming Dynasty. Xu Da was born in a peasant family. At the end of Yuan Dynasty, Xu Da joined the uprising army led by Zhu Yuanzhang, and was one of the twenty-four generals in Huaixi. In the 23rd year of Yuan Dynasty, Chen Youliang was defeated in the battle of Poyang Lake. The following year, he was appointed as Zuo. In the 25th year of Zheng Zheng, Huishi captured Huaidong, and two years later conquered Pingjiang and destroyed Zhang Shicheng.

Soon he became a general of Lu and went to the Northern Expedition with Chang Yuchun, the lieutenant. In the first year of Hongwu, it invaded Dadu and overthrew the rule of the Yuan Dynasty. Since then, he has sent troops to attack the remnants of the Yuan court in successive years, incorporated Shanxi, Gansu and Shaanxi, and greatly expanded the Kutemur Department. Only the battle of Lingbei was defeated because of him alone. Hongwu stayed in Beiping for a long time after six years, training foot soldiers, cultivating land, repairing the city defense and consolidating the border defense. Tired of being a teacher, the right prime minister wrote a book, joined the army, served as a prince and a little fu, and sealed Wei Guogong.

Xu Da died in the eighteenth year of Hongwu at the age of 54. Zhu Yuanzhang was named King Zhongshan, posthumous title "Wuning" and buried in Shanyin; He also made a tombstone for him, asking him to paint the hero temple and enjoy the ancestral temple. Xu Da was cautious, was good at running the army, and served as a soldier all his life, making immortal contributions to the establishment and consolidation of the Ming Dynasty. Zhu Yuanzhang became the "Great Wall of Wan Li" with it, and later generations also recognized him as the first hero of the founding of the Ming Dynasty, ranking first among the "six heavenly kings".
