King wen made Taigong the magistrate of Guantan. During the year Taigong was there, there was never a wind that was strong enough to disturb the leaves of the trees. Once in his dream, King Wen saw a beautiful woman weeping before his carriage.
When asked the reason, she replied, "I am the daughter of the god of Mount Taishan and married to the god of the East sea. Now I want to go home, but the virtuous magistrate of Guantan makes the trip difficult. For my movements are always accompanied by a violent storm, which damage his good name." After waking up, the king summoned Taigong to ask what had happened. He was told that a violent storm with pouring rain had swept areas outside Guantan that day. King Wen then promoted Taigong to the position of Chief General. - From Sou shen ji (Stories of Immortals)
