Gao Bingyan embraces her father amidst tears in the Caiyuanba Railway Station in Chongqing.

"My dear father, I want to share with you a lot of things. I can still recall my hatred towards you at the age of six. At that time, I cried a lot and wished you would turn around and look at me, but you just walked away, determined to earn money in the city. When I grew older, I realized you had gone through many difficulties to support our family," said Gao Bingyan to her father, Gao Yongke, in tears.

On Jan. 4, 2016, 18 migrant workers took train number K1248 from the Ningbo railway station to their hometowns in Chongqing. Gao Yongke is one of them.

In 2016, 500 migrant workers who were born in Chongqing were able to use train tickets bought by the Chongqing welfare lottery center to return to their hometowns.

Gao thought about nothing else besides his daughter on the train home, and counted down the minutes until he could see his daughter in person.

Gao knew the train was expected to arrive at Chongqing Caiyuanba Railway Station on Jan. 6. He got up quite early on that morning and talked with a neighboring passenger to pass the time.

The closer he got to his hometown, the more homesick Gao became.

After more than 40 hours of travel, Gao finally reunited with his children on the platform of the railway station. 

Gao Yongke and his wife hold a birthday party for their daughter after her actual birthday, once they arrive home.
