"My father spent six years in prisons in Assam, Ajmer,

Delhi before the Punjab and Haryana High Court ordered his release in March 1969," Vishnu said.

"The Indian government had promised to the court that it will rehabilitate my father. He was taken to Delhi, Bhopal, Jabalpur and then finally handed over to Balaghat police," said his son.

Wang started working as a watchman with a mill and soon his colleagues named him Raj Bahadur, apparently due to his Nepali features, Vishnu said.

Wang's mother died in 2006 but he could not be with his dear ones in the time of grief, Vishnu said.

Three years later he met his nephew Yun Chun, who had come to India as a tourist and narrated his ordeal to him.

After returning home, Chun got in touch with Chinese politicians and authorities to bring his uncle home.

Finally, he met then Chinese Foreign Minister who helped Wang to get a Chinese passport in March 2013.
