    Online live streaming(直播) is big business nowadays, making huge profits and attracting hundreds of millions of viewers. In addition to adults, this rapidly expanding industry is now drawing underage live streamers, who are not of legal age. According to a report by the Sina Weibo Data Center, live streamers aged 11—16 accounted for 12 percent of all streamers in China. The figure has been rising still, while streamers are getting younger.

It has been found that a large number of underage streamers are drinking, smoking or even exposing to attract viewers. In the best case, live streaming will affect children’s schoolwork and waste their precious youth. In the worst case, they will develop bad values and an improper outlook, which will damage their future.

“Webcasts (web broadcast) are suspected of having a hotbed of improper program. Particularly, the involvement of underage streamers in this industry is making the situation more complex” said Mao Jianguo from Southern Metropolis Daily.

Some legal experts recently issued a report on protection of the children in the cyberspace(网络空间), suggesting that those under 14 should be restricted from independently live streaming and posting videos online.

However, it is unwise and impossible to totally reject all underage streamers but it's necessary and even urgent to standardize the underage webcast sector.

Fortunately, some webcast companies have said that they will not allow streamers under the age of 18 and online live streamers must register by using their ID. However, the reality is that many underage streamers choose to avoid that by using the IDs of adults, who also go through the face scanning required for conditions. All this means that to block underage streamers from webcasting, it’s not enough to depend on their self-discipline.

Parents should tell their children about the disadvantages of getting involved in live streaming so that children develop an objective attitude toward live streaming. Adults should not lend their IDs to children to register for live streaming. And the watchdogs must patrol(巡逻) webcast platforms more actively and remove all unauthorized videos of underage streamers.
