A screenshot from a video uploaded by YouTuber "girit" shows a man in red, who appears to be a Changbai Mountain working staff member, stopping the YouTuber from displaying a South Korean national flag in the mountain, Northeast China's Jilin Province.

A video clip of a man waving the South Korean national flag, who was stopped on-site at the Changbai Mountain in Northeast China's Jilin Province, has sparked discussions on Chinese social media Sina Weibo on Thursday, with some netizens urging tourists to respect China's laws and regulations.

The original video was uploaded on July 25 by a YouTuber named "girit." The more than four-hour-long video showed the YouTuber livestreaming his trip to Changbai Mountain. While at the top of the mountain, viewing Tianchi Lake, he took out the South Korean flag and sang its national anthem. Then, a man in red who seemed like a working staff of the mountain appeared in the video, took the flag, and stopped the YouTuber.

According to the video, some South Korean tourists at the scene said that this is Chinese territory and he cannot do that kind of thing. 

South Korean news channel YTN reported the incident on Wednesday.
 
On Thursday, the Global Times inquired with the Jilin Changbai Mountain Protection Development Management Committee about the incident. A staff member confirmed the incident happened in the northern section of the scenic area, but did not disclose the exact time.

The staff member said the local public security bureau had handled the case. Similar incidents occurred before, and staff have always intervened promptly, according to the working staff. 

The video clip sparked discussions on Sina Weibo on Thursday, with some netizens praising the scenic area staff, and others criticized the tourist's behavior and called for respect for China's laws and regulations.

According to provisions of China's Foreign Ministry on foreign-related display and use of national flags, foreign individuals in China are generally prohibited from hanging foreign flags outdoors or in public spaces, except on events like a foreign country's national day, during which the Chinese national flag should also be displayed alongside it, according to a release on the website of the Ministry of Justice.
