"Unruly fans causing chaos at the airport disrupts social order and security. Selling and paying for celebrities' flight information also breaks rules on personal privacy," wrote People's Daily on its official Sina Weibo account on July 24.

This May, when Taiwan pop singer Hebe Tian, a member of Taiwan pop group S. H. E, was welcomed by dozens of her devoted fans, at the airport of Hangzhou, Zhejiang province, she told fans to be safe and to clear the way. Later, she described her experience at the airport as "Too much" on Sina Weibo.

In a public letter written by fans of Chinese pop singer Cai Xunkun early this May, they say that "out of respect and protection for Cai Xunkun, please don't obtain any information about his private schedules. It will cause trouble for him and disturb social order."

The 19-year-old Cai rose to fame after participating in a reality show, Idol Producer, launched by China's online streaming service, iQiyi, early this year. He won a total of over 47 million votes and made his debut with the pop group, Nine Percent, this April.

Now, Cai has about 12 million followers on his Sina Weibo account and is one of the most popular young pop stars in the country.

"I became a big fan of him after I watched the live performance of the final competition of Idol Producer on April 6. He is so talented and so cute," says Qi Qi, a 20-year-old woman from Beijing, mentioning that fans of Cai are nicknamed "ikun", meaning "love kun".

"Since Nine Percent started touring nationwide, I traveled with them. I only go to the concerts, fans meetings, and other public events. I don't want to disturb his life."

Qi also notes that she has seen other fans following their idols through the airport, which "just look's so crazy."

"Some fans shove their phones in the stars' faces, which is not polite. It also caused some of the fans, and the stars themselves, to be pushed and even injured in the process. Security is necessary to protect both the celebrities and the other people," she adds.
