The calligrapher Wang Xizhi is famous for his calligraphy. One New Year's Eve, he posted several couplets on the door, but they were all taken away. So, this time he wrote a four-character couplet,
Blessings are unparalleled,
Wa does not travel alone.
I complained about having my contacts stolen twice. When others saw that it was not auspicious words, no one said it again. In the evening, Wang Xizhi added three characters to the upper and lower couplets, and it became,
Fu Wushuang has come to this day,
Wa does not walk alone in heaven.
