The 77-year-old is thought to be keen "on spending the last years of life in China" as one acquaintance said, but his wife remains in India, where his son and daughter and their families reside.
While the Chinese government has provided visas for his family to visit China, India has provided a re-entry visa for Wang to return back if he chooses to.
Indian officials, who accompanied Wang, said he and his family have stayed put at a hotel in Xian and have not visited his village which is about 100 kms from there.
While Wang has made the best of his unexpected predicament, marrying a local girl and starting a family, he has long wished to travel home to see his family in China; however, he had curiously been denied official Indian documents and citizenship time and again. The local government has said they would make land and a home available for Wang in his home village and given the widespread coverage that Wang Qi has received from media outlets in China, there is unlikely to be any shortage of help and support should he return.
The Chinese embassy was able to secure a passport for him in 2013 but his family say he was still unable to leave the country without an Indian exit visa.
"China appreciates the facilitation provided by relevant authorities of the Indian government in this process", he added.
He flew out from Delhi on Friday night accompanied by his son.
He landed in Assam where an Indian Red Cross team handed him over to the Indian Army on January 1, 1963.
He spent the next seven years in prison before a court ordered his release in 1969 and took his to Tirodi in the central state of but did not allow him to leave the country.
"I have heard that Wang Qi was felicitated in China and several people came to meet him". Wang married Sushila in 1975 but his desire to live a comfortable life was short-lived. "My father and family are very happy after reaching China. He tried very hard and even entered into correspondence with the then Prime Ministers but in vain", he said.
"His life has been hard as he couldn't get Indian citizenship because of his Chinese origin". His mother died in 2006.
Three years later he met his nephew Yun Chun, who had come to India as a tourist and narrated his ordeal to him. Now he is finally due to his home after 50 year of rough survival in India.
Wang said he had been trying all this time to return to China, but his request went unanswered and he could not obtain an Indian passport.
