The next year, in 618 BC, Wei, the Count of Mao (毛伯衛), a Zhou official, went to Lu to "request" for tribute.
Gongyang Zhuan notes that the Spring and Autumn Annals used such wording as a mockery, pointing out that "kings do not make requests.
In 616 BC, Souman (鄋瞞), a Di tribe, attacked Lu after an invasion of nearby Qi.
Duke Wen ordered Shusun Dechen (叔孫得臣), a minister of Lu and a member of the powerful Three Huan clans, to fight the Souman.
On 9 September 616 BC, Shusun Decheng defeated the Souman army at Xian (咸), capturing and executing its leader Qiaoru (僑如).
