Later in 937, Wang ordered his younger brother Wang Jigong, whom he had given the title of military governor of Weiwu, to submit a petition to Shi Jingtang, the emperor of Later Jin (which had overthrown and replaced Later Tang), reporting his own succession to the throne, and requesting that a liaison office be established at the Later Jin capital Kaifeng. (In other words, Wang Chang himself did not want to show personal subordination to Shi, but did want to show submission on a state-to-state basis.) Shi reacted by issuing an edict in 938, creating Wang Chang to be the King of Min (i.e., not emperor) and Wang Jigong the Prince of Linhai, sending his official Lu Sun () to deliver the edict. When Wang Chang heard this, he had his emissary Lin En () explain to the Later Jin chancellors that, because Wang Chang had claimed imperial title, he did not want to be created a king and did not want Later Jin's imperial emissary to come to his realm. When Lu nevertheless arrived in his realm in 939, Wang Chang refused to meet him and claimed to be ill, and instead had Wang Jigong serve as Lu's host. He nevertheless sent his official Zheng Yuanbi () to accompany Lu back to Later Jin and to offer tributes to Shi.
