The couple who added a 10 yuan ($1.61) surcharge to the price of the train tickets they bought online to sell to migrant workers in Foshan, Guangdong province, were released on bail on Wednesday.

Zhong Quanzhen and his wife Ye Xia were detained by officials of the Zhaoqing division of the Guangzhou Railway Public Security Bureau on Jan 13 for ticket-scalping. Police found 212 train tickets, with a total face value of more than 35,400 yuan, and 213 ID cards in their store.

According to railway regulations, anyone selling train tickets who charges more than 5 yuan for each ticket is ticket-scalping.
