   Tencent announced yesterday that it would limit the daily time for youngsters to play its popular King of Glory game after parents in Shanghai and other areas complained their children had become addicted to playing it.

"From tomorrow，children younger than 12 will only be allowed to play the game for a maximum（最大值）of one hour a day，and after 9 pm，they will be banned from logging in it，"said Tencent."Those older than 12 will be able to play a maximum of two hours a day."

The game system will remind players the time they have been playing and young players will be forced to log out when the time is up.

Tencent claimed these were the strictest measures in China's game industry to prevent addiction and the company expected they would ease parents' anxiety.

The company also said it had updated its system for parents to keep tabs on their children using its games.

Since February，parents can receive messages when children log in and spend money on the game after they connect children's game accounts with their mobile phone numbers.

"Now, parents can connect phones, tablets or computers that their children use to play games, so that they can keep an eye on the children even if they have several game accounts," Tencent said.

Song Zhe, a father of a Shanghai high school student, welcomed the measures but was not sure if they would be sufficiently effective." I like the system that could lock up the devices as children can register many accounts," he said, "but children are so clever that they can always think out counter measures."

   Searching for airfares often seems like a game that passengers are bound to lose.

Prices change from day to day, even minute to minute. Looking through various websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.

“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog. com.

Harriet Levy paid $ 179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $ 215. A few rows back, Ellis and Dianne Traub paid $ 317 each. There were at least 12 fares on the flight, ranging from $ 169 to $ 360.

“There’s no reason for it,” Harrison said.

Fares can vary significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $ 755 to $ 1,143 from a Friday to Saturday in late April, and then fell to $ 718 on Sunday.

The flight was one of a dozen the Associated Press（美国联合通讯社）followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.

There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:

● Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.

● Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are the highest when tickets are booked eight to ten weeks and two to three weeks in advance.

● Make use of social media. Airlines are giving more benefits like exclusive（专有的）sales to travelers who interact（交流）with them on Twitter and Facebook. Those specials are often gone within hours.

● The so-called discount airlines — JetBlue, Air-Tran, Southwest and Frontier — adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.
