In 922, there was an incident where Liu Yan (whose state had been renamed Han by that point and thereafter was known as Southern Han in traditional Chinese sources), believing in sorcerers who told him that he should go to Meikou (梅口, in modern Meizhou, Guangdong) to avoid a disaster. With Meikou on the border between Southern Han and Min, the Min general Wang Yanmei (), who might have been either a son of Wang Shenzhi's or Yang Shengui's, decided to launch an ambush on Liu. However, Liu received news of the ambush and left Meikou before Min forces could attack.
