After Tang returned to Shang, the painful experience of being imprisoned made him more determined to destroy the Xia Dynasty, and he saw that more and more people rebelled against Xia and returned to Shang, so he discussed with Yi Yin and Zhong Yu about the conquest of Wei and Gu. After some planning and preparation, Tang and Yi Yin led the armies of all parties to help the Shang State and attacked the Wei State first. Tang led a large army to press the border, and Wei did not even have time to ask for help, and was soon destroyed by the merchant army. The State of Wei was destroyed, Gu Guo was alone, and Tang then marched eastward, and took advantage of the victory to destroy the Gu State. The land, property, and people of Wei and Gu were all owned by the Shang State.

Xia Wei did not raise an army to conquer the Shang State because of this, and a year later, the Kunwu State relied on its ability and led an army to attack the Shang State. Yi Yin saw that Kunwu was desperately loyal to Xia Wei and was bent on making enemies of Shang, so he asked Tang to lead his army to meet Kunwu. The Shang army defeated the Kunwu army, and soon the Shang state destroyed the Kunwu state. Tang also took Yi Yin's advice and stopped paying tribute to the Xia Dynasty in order to test Xia Wei's strength. This news reached the Xia capital, and Xia Wei immediately summoned the army of Jiuyi to attack the Shang State. Shang Tang saw that Xia Jian could still mobilize the forces of the Jiuyi Clan, and knew that Xia's power was still very strong.

Shang Tang knew that the time was not right, so he immediately pleaded guilty to Xia Wei, prepared a generous gift to express his surrender, resumed the tribute, removed the mustard in Ji's heart, and won the time to wait for the opportunity. A year later, because of the capriciousness of the Ji, the leaders of Jiuyi also saw that Xia Ji would not last long, and in the end they did not listen to Xia Ji's dispatch. The Jiuyi tribe could not endure the brutal rule of the Ji, and rebelled one after another, and the power of the Ji was greatly weakened.

In 1766 B.C., Shang Tang swore an oath in Jingbo and declared Xia Wei's crime. Shang Tang officially raised troops to defeat the Xia Dynasty. Tang Hezhongyu and Yi Yin led an army of 70 chariots and 5,000 foot soldiers to the west to attack Xia Wei, who mobilized the army of the Xia Dynasty and drove out of the royal capital. The two armies of Xia and Shang met in the field of Narujo and started the battle of the Great Assembly.

Before the battle began, in order to boost morale, Tang summoned the Shang army who participated in the battle and the army of the princes and Fang who came to help the Shang State destroy the Xia Dynasty, and read an oath to conquer the Xia Dynasty. After Tang's mobilization, the morale of the Shang army was greatly boosted, and they all expressed their willingness to fight to the death with the Xia army. Xia Jun was demoralized and resentful. On the day of the battle between the two armies, it was just in time for the thunderstorm, and the Shang army did not avoid the thunderstorm and fought bravely, and the Xia army was defeated and retreated. Xia Wei saw that the defeat was out of control, so he hurriedly led the remnants of the army to escape. Tang and Yi Yin led the army in hot pursuit, and finally in Nanchao, the merchant army captured Xia Wei. Tang exiled Xia Wei in Tingshan in Nanchao, and in the third year after the establishment of the Shang Dynasty, Xia Wei died of grief and illness in Tingshan.

In order to completely eliminate the remnants of the Xia Dynasty, Tang and Yi Yin continued to lead their army westward. Because some of the more powerful Fang states such as Wei, Gu, and Kunwu were all destroyed by Shang Tang, the Shang army did not encounter great resistance on the way west, and soon occupied the Xia capital, and the pro-noble ministers of the Xia Dynasty expressed their willingness to surrender to Tang. After Tang and Yi Yin pacified the subjects of the Xia Dynasty, they held a ceremony to worship the heavens, indicating to the subjects of the Xia Dynasty that they were coming to punish the guilty Xia Ji according to the will of the heavens, and the Xia Dynasty's qi had been exhausted, thus officially announcing the end of the Xia Dynasty.

Tang and Yi Yin in the summer capital after the sacrifice to heaven and earth, led the army back to Bodi, at this time the prestige of the Shang State has reached the four directions, the princes of all over the country, Fang Bo and large and small clans, the chiefs of the tribe have brought tributes to congratulate, expressing their submission to Tang, within a few months, there are 3,000 princes to come to Bodi.

After twenty years of conquest and war, Tang finally destroyed the Xia Dynasty, unified the Central Plains that had been in turmoil since the end of the Xia Dynasty, and controlled the middle and lower reaches of the Yellow River. Even the Dī and Qiang tribes living in the western region came to the court, saying that Shang Tang was their monarch. After Tang destroyed the Xia Dynasty, he laid the foundation of the Shang Dynasty's territory. Shang Tang destroyed the Xia Dynasty by force, breaking the theory of king Yongding, and since then all Chinese dynasties have changed in this way.

"That" is the first poem of the "Song of Shang", and like several other poems in the "Song of Shang", it is an ode to the ancestors of the descendants of the Yin Shang dynasty. Judging from the poem "That", there is no special content in the poem to sacrifice Cheng Tang, but it describes the situation and scene of the sacrifice in the Shang Dynasty, which is probably the welcome song of the ancestors of the Shang Dynasty, including Cheng Tang.

Unlike most of the poems in the poem, the poem "That" mainly shows the music and dance activities of sacrificing ancestors, using the grandeur of music and dance to express respect for the ancestors, so as to seek the protection and blessing of the ancestral gods. There are four kinds of musical instruments that appear in the poems: standing drums, pipes, chimes, and bells, which belong to the four categories of leather, bamboo, stone, and gold in the eight-tone classification of ancient Chinese musical instruments, and there is one kind of dance: ten thousand dances.

The drums used in the poems are táo drums, and according to the literature, there are two types of táo drums: one is a large erection set called a standing drum; A small one similar to today's rattle. The drum in the poem is supposed to be a standing drum, and its function is to dance happily at the beginning of the sacrificial song and dance. And the sacrificial dance is ten thousand dances, ten thousand dances, we mentioned before, in "Shao Feng Jianxi": the drums are beating loudly, and the dancers are going to perform ten thousand dances; The sun is shining high, and the dancers are in front; Who is the person I miss in my heart, it is the beauty of the West; The Western beauty is so handsome, he is a person from the West.

It's so beautiful, so rich, put a standing drum on my hall. Beat the drum and make my ancestors happy. The grandson of Shang Tang is offering sacrifices and giving me success to pray for my ancestors.

The standing drum is fluffy, and the wind music is whining. The melody and harmony are clear and flat, and the chime rhythm has ups and downs. The grandson of Shang Tang is really prominent, and the music is harmonious and beautiful.

The bells and drums rang loudly in unison, and the scene was grand to see ten thousand dances. I help to make good sacrifices to the guests, and they all rejoice in one place. In that distant ancient time, the ancestors had a law for their deeds.

Gentle and respectful in the morning and evening, worship the gods and pray for blessings. Please accept the ancestors' offerings, and the descendants of Shang Tang will be blessed.
