A dance routine performed by middle school students in southern China caused controversy as it included them lifting up their T-shirts.

In the video, shot in the city of Guiyang in Guangxi Zhuang Autonomous Region on September 28, several girls lifting their tops up to show their bras when they were performing a dance at Yangshuo No.2 Middle School's sports meeting.

The video has caused controversy after it went viral on Chinese social media.

One netizen said: "It is inappropriate to do this on a school's sports meeting as they are all underage."

While another one said: "There is nothing wrong with the dancing movements. But underaged students dancing like that to expose their underwear in public was inappropriate."

However, some people thought it was not a big issue. One netizen said: "I think it is very normal."

The school principal said: "The students choreographed the dance themselves and their dancing movement range was not that big during the rehearsal. However, the school will check more strictly on the students' dancing movements in the future."

近日，广西桂林阳朔县阳朔镇第二中学（初级中学）举行运动会入场式表演中，学生跳舞时撩上衣，露出黑色内衣。该中学校长回应，舞蹈是学生自己编排的，有舞蹈老师审查，审查时学生撩衣幅度不大，以后在舞蹈编排上会更严格。（视频由广西台提供）
