Hit travel reality show ventures abroad to Laos

HAHAHAHAHA puts spotlight on railway that brings guests between countries with ease, Li Yingxue reports.

After school classes finish, 17-year-old Khan Sing usually heads to Xinhua School in Luang Prabang, Laos, for his usual Chinese lessons, but today is different. The class welcomes two special guests — Chinese actor Deng Chao and rapper After Journey.

The duo teach the students to sing the Chinese song Tomorrow Will Be Better, with some of them quickly learning to sing it fluently.

Khan also has an arm-wrestling match with 45-year-old Deng and wins. "I think Deng was stronger; he was letting me win. Interacting with him was incredibly exciting and made me very happy," Khan says.
