It is a feudal superstition that if you get married by riding a dog, it will rain. It has no scientific basis. Raining at a wedding is just a natural phenomenon and has nothing to do with whether you have ridden a dog. The allusion of getting married by riding a dog and making it rain comes from Chinese folklore. Its story probably means:

< p>A long time ago, there was a beautiful girl named Xiaoying, and she had a loyal dog named Xiaowang. Xiaoying's sweetheart is a handsome knight named Xiaoming. Xiao Ming is riding his war horse, handsome and majestic. Xiaoying's sweetheart also likes Xiaoming very much. They like each other and are ready to get married.

However, just when they were about to go to the church, it suddenly started to rain heavily. The sky was filled with dark clouds, it was windy and rainy, and there was lightning and thunder. Xiaoying and Xiaoming had to cancel their wedding and ride their horses and dogs home. Although the weather was bad, Xiaoying's sweetheart still thought of her Xiaoming. They kept in touch and agreed to visit the church again on the next sunny day.
