Video of a man rocking a blooming cherry tree sparks online backlash

As the weather gets warmer, cherry blossoms have come into their own at locations around China.

Known for its more than 1,000 blooming cherry trees, Wuhan University in central China's Hubei Province has attracted hordes[1] of visitors to its annual cherry blooming festival, running from March 20 to April 2.

In the video first released on Yishou Video, a young man was seen crossing the fence and fiercely shaking a cherry tree to make its flowers fall, amid laughter and cheers from his companions.

Taken at the campus's famed Cherry Blossom Boulevard[林荫大道], the man was on the point of shaking another tree but by that time, an incensed crowd reacted and someone pulled the culprit[4] off the tree.

According to a witness, the man was so infuriated that he was about to hit the person who stopped him but was prevented from doing so.

Later that day, the university posted a video on its official Weibo account calling on the public to protect the cherry blossoms, saying "Is the rain of cherry blossoms beautiful? The flowers hurt a lot."

The post has generated much anguish from netizens as well as students. Some said people should be given a fine for that type of behavior; one student even said they hoped the school would cancel the annual festival.

Many visitors rushed to the campus as a result of the incident, causing some inconvenience to daily teaching. On Mar. 22, to shelter from the rain, some visitors even got into a teaching building, forcing the early dismissal of a class.

To tackle the situation and to cap[5] the daily number of visitors, Wuhan University had already set up an online booking system, with the capped[有上限的，封顶的] number set at 15,000 on weekdays and 30,000 at weekends. Visitors have to swap their ID cards and facial recognition systems before entering the campus.

The school also said that visitors who behave in an "uncivilized" manner while visiting would be blacklisted and banned.
