In summer 570 BC, Duke Xiang, then six years old (in
East Asian reckoning), visited the Jin court for the first time. When paying respects to
Duke Dao of Jin, Duke Xiang
knelt and touched his forehead to the ground, a formality reserved for the
Son of Heaven. , a Jin official, commented about this, while Zhongsun Mie, who accompanied Duke Xiang, replied, Because our humble settlement is on the eastern rim and in close proximity to our enemies, it is to you, my lord, that our unworthy ruler must look. How should he dare not bow with his forehead touching the ground?Lu remained aligned to Jin throughout Duke Xiang's reign. He would visit Jin four more times: in 569 BC, in 565 BC, in 561 BC, and in 552 BC. On 28 June, 569 BC, Ding Si died. She was laid to rest on 21 July of the same year. In winter 569 BC, Duke Xiang visited the Jin court once again. Zhongsun Mie requested that the nearby state of Zeng (鄫; not to be confused with 曾) be "made subordinate to" Lu. When Duke Dao of Jin refused, Zhongsun Mie appealed to Lu's commitment to the alliance and Zeng's failure to provide troops to Jin, claiming Lu's fear of causing offense to Jin should it fail to provide. Duke Dao of Jin was convinced and granted Lu's request. Soon later, nearby states of
Zhu and
Ju attacked Zeng. Lu official led an army to rescue Zeng, but was defeated at Hutai (狐駘). The
Zuo Zhuan notes that the people of
the Lu capital mourned the dead by tying their hair with hemp strings, starting a tradition. Ju would fight Lu again in 561 BC, 559 BC, and 558 BC. After swearing a covenant at Duyang (督揚), Lu and Ju would not fight again during Duke Xiang's reign. However, hostilities would resume in 538 BC. In summer 568 BC, presented Crown Prince Wu (巫) of Zeng to Jin in order to formalize Lu's subjugation of Zeng. However, Ju conquered Zeng in 567 BC, while Lu did not intervene. The precise reason was not recorded in history, but it was recorded that Zeng "was relying on bribery for protection." Jin sent an envoy to Lu, demanding an explanation of Lu's failure to defend Zeng. went to the Jin court to provide such explanation. In the same year, Shusun Bao visited Zhu to improve relations between Lu and Zhu, with the Zeng dispute becoming a moot point. However, Lu and Zeng had another border conflict in 565 BC. In summer 566 BC, the Jisun clan fortified its settlement Bi (費). In winter 564 BC, Lu, represented by an army led by Jisun Su as well as Duke Xiang himself, participated in another coalition led by Jin, this time attacking Zheng, which quickly sued for peace. The leaders of Jin decided to accept the peace deal and swear a covenant with Zheng in order to lure Chu, which Zheng was aligned to, into attacking Zheng. Then, the coalition forces would be able to fight the Chu army, which would be tired out, with fresh forces. The peace deal was finalized on 11 October, 564 BC, with Zheng switching its allegiance to Jin. However, after the deal was finalized, Zheng managed to reinterpret the wording of the peace terms from complete submission to Jin to one conditional to Jin's policies. The Jin coalition, with its strategic goals unfulfilled, attacked Zheng again soon after, but then withdrew. Zheng then quickly switched its allegiance back to Chu. It was soon after the Zheng campaign when Duke Xiang, aged twelve, completed his
capping ceremony, signifying that he became an adult. Protocol required that the ceremony be conducted at the ducal house's familial temple. As he was away from Lu, Duke Xiang used the temple dedicated to
Duke Cheng of Wey, which was on his way back to Lu.
Intervention of Song Factional Dispute In autumn 576 BC, died. ,
Song's
Master of the Horses of the Huan (桓) lineage, murdered Crown Prince Fei (肥), while Minister of the Right of the Dai (戴) lineage attempted to flee to
Jin. However, by the banks of the
Yellow River, Hua Yuan was personally stopped by Minister of the Left Yu Shi (魚石), another member of the Huan lineage, who feared that Hua Yuan might annihilate the entire Huan lineage should he return with an army and believed that he would kill only Dang Ze should he stay. Yu Shi predicted correctly, but all five ministers of the Huan lineage, including himself, fled to
Chu, Hua Yuan's request to stay notwithstanding. Hua Yuan then made Prince Cheng (成), a younger son of Duke Gong, the Duke of Song. Prince Cheng would become known as
Duke Ping of Song. In summer 573 BC, Chu and
Zheng attached Song, seizing
Pengcheng and sending the five exiled ministers there. As efforts to retake Pengcheng faltered due to continued Chu reinforcements, Hua Yuan went to Jin for help. Although a Jin army sent to Song to keep Chu power in check defeated a Chu army at the Valley of Mijiao (靡角之谷), further military campaign was necessary. It was at this point that Jin sent an envoy to Lu for aid, which Lu agreed to give. In spring 572 BC, a Lu army led by joined a coalition force led by
Jin Minister to attack Pengcheng. The siege was successful, with Jin capturing the five Song ministers and bringing them back to Jin. == Middle reign ==
