The government notice described it as a "corrupt custom" that in the worst cases resulted in "injury or even death".
Although the rituals observed today were rooted in a tradition that dated back thousands of years and intended to expel evil spirits, they had since lost their meaning, it said. Therefore anyone who engaged in them should be punished.
The warning was extended to local officials who were encouraged to set a good example.
Last month, a bridegroom in Tangshan, a city in neighbouring Hebei province, was made to wear women's underwear and stockings, and then tied to a tree by his friends.
A video of the event that widely circulated on Weibo, China's Twitter-like service, showed him being doused with bowls of black sauce and flour by the wedding guests.
In their defence, the man's friends said he had done the same to other grooms on their big day.
In November, a 24-year-old groom in south China's Guizhou province suffered a fractured skull after being hit by a car while trying to flee a hazing ritual.
His friends had earlier thrown eggs at him, covered him in beer and ink, tied him to an electricity pole and thrashed him with bamboo sticks.
In December, the government vowed to crack down on hazing rituals at weddings, describing them as a sign of "declining morality", as well as the traditions of staging extravagant ceremonies and buying expensive gifts.
