Urgūdai

Ancient Wu'er was called Urgūdai in Manchu; in Chinese, it was also referred to as Wu'er, and due to its status as Dun Tang, it was called "Dutang." Because it was the daughter of Nurhaci, Manguci's husband, it was also known as the "Ebu." Its ancestral lineage was from the Hadanaala clan, and it was the son of the last Hadar ruler Menggebulu. Wu'er served as Dutang. After marrying Manguci, it was often presented under the surname Wang.

The main points of its life are as follows: In 1599 (the 27th year of Wanli), Jianzou captured Hadacheng; Wu'er and her father Menggebulu were both taken captive. Menggebulu was shortly afterwards executed. In January 1601, Nurhaci married Manguci to Wu'er as his wife. The news of Menggebulu's death reached the Ming court, and Emperor Shenzong of Ming issued a decree to Jianzou, condemning Nurhaci for seizing Hadach and killing Menggebulu, and revoked his rewards. Nurhaci claimed to obey the decree and expressed his willingness to return Menggebulu's son Gebaku and his 120 households, and vowed support beyond Fushun Pass through the White Horse League, promising to safeguard Wu'ergu's territory; Yeghe Beile Nalan Bulu also returned the original six decorated edicts taken. Nurhaci ordered Wu'er to return with all the people and soldiers to live in Hadach. Due to repeated attacks on Hadach by Yeghe and the famine there, and with limited assistance from the Ming, Wu'er defected to Jianzou.

Regarding other familial relationships, Nurhaci had also married the daughter of Shurhaci to Wu'ergu's younger brother, Morohun. Morohun was unruly and did not nurture well, resulting in tense relations between the brothers; Shuotuo was also mistreated by his father, what was called Shi Da Shan. In September of the fifth Year of Tianming (1620), Shuotuo and Morohun conspired with Shurhaci's son Zhai Sanggu to defect to the Ming. On the 13th day, Nurhaci, seeking to investigate these matters, ordered Wu'ergu to inquire about the details. Wu'ergu expressed distrust of his brother's actions and provided information. Subsequently, the statuses of Zhai Sanggu, Shuotuo, Morohun, etc., and how they were dealt with varied during follow-up interrogations: Shuotuo was released; Morohun and his wife were executed.

In March of the sixth Year of Tianming (1621), Later Jin captured Liaoyang, Anshan, Haizhou, and other cities, and officials and commoners throughout Liaodong surrendered in large numbers. On the first day of May, reports spread that people from Liaodong had shorn their hair and submitted, while Zhenjiang residents refused to shave and murdered envoys. Wu'ergu's deputy, acting under his father-in-law’s orders, with deputy Fushun Li Yongfang leading a thousand soldiers, went to investigate the situation, compelled Zhenjiang to surrender and shave, took a thousand of their family members captive, and returned on the 25th day. Nurhaci, upon hearing this, selected 300 Han Chinese to be awarded official posts below the commandant level of the Dutang, and redistributed 600 captives to the accompanying soldiers.

On the sixth day of the ninth month of Tianming (1621), Tangzhan Shoubao reported to Nurhaci that those who had surrendered within the territory were being attacked; Later Jin dispatched Wu'ergu, Li Yongfang, Tong Yangxing, and three other officials out of the city to welcome the envoy of King Guang. On the seventh year of Tianming (1622), the 13th day of the first month, Wu'ergu was bestowed six small flags, an umbrella, and a horn. On the 28th, he was granted a camel and fourteen pieces of brocade clothing. On the third day of the second month of the seventh Year of Tianming (1622), Wu'ergu participated in the Battle of Guangning with his son, born of Manguci, named E'erdeni, who fell from his horse and died. Nurhaci ordered Niu Lu to send someone to deliver his body to Liaodong and personally mourned him.
