Many youths in big cities such as Beijing, Shanghai and Guangzhou like to hold parties on the day or go to bars to enjoy themselves in twos and threes.

More than five thousand passengers were affected by the breakdown on the eleventh running day of the Beijing-Shanghai high speed train.

The Beijing-Shanghai high speed train was delayed again at noon on Tuesday due to a breakdown of the electricity supply.

The report said that the sensors, produced by a foreign company it didn't name, may have caused stoppages on the Beijing-Shanghai route in July.

Instead, it's the airlines that offer service between Beijing and Shanghai.
