Editing Later Yan (section)

=== Wars with Zhai Wei and Western Yan ===
In 386, Murong Chui made Zhongshan (中山, in modern [[Baoding]], Hebei) his capital, as the city underwent significant development during the war. Later that year, his cousin, [[Murong Yong]] of Western Yan occupied [[Shanxi]] and declared himself emperor. By now, both Murong Wei and Fu Jian had died, so Chui also changed his title to emperor. The Dingling rebels under [[Zhai Liao]] founded the [[Zhai Wei]] state at Huatai (滑台, in modern [[Anyang]], [[Henan]]) in 388. Rebellions frequently broke out in Yan territory, and the Yan was in a constant state of warfare.

In 392, Murong Chui campaigned against and destroyed Zhai Wei. In 394, seeking to establish Later Yan as Former Yan's true successor, Chui began a campaign to conquer Western Yan. He captured the Western Yan capital and executed Murong Yong, annexing Shanxi for Later Yan. Then, he sent his generals to capture Shandong from the Eastern Jin dynasty, bringing the state to its peak.

At this point, Murong Chui was already at an advanced age, and so he began empowering his Crown Prince, [[Murong Bao]]. In 388, he assigned Bao to run the government from Zhongshan while still retaining his decision-making power on important matters. Chui also introduced a separate governing system between his Han Chinese and "Hu" subjects within Yan by appointing Bao the Grand Chanyu, tasked with supervising the tribes. This system was further developed during the reign of [[Murong Sheng]], who established the Yan Ministry to manage the tribes, and then [[Murong Xi]], who set up the Grand Chanyu Administration.
