The above c.1912 Tientsin map identifies the location of a Sikh temple. J J Singh of Kapurthala royal family, mentioned in his writings, of Sikh policemen stationed in Tientsin, approaching him for funds for a gurdwara. Then there is a picture of 2 Sikh soldiers/policemen, where one of them is holding a chaur used ritually for the holy book Guru Granth Sahib.  

Unfortunately, I haven’t come across any photographs of the Tientsin/Tianjin gurdwara. Yet. Again, the topic requires research and fact-finding to ascertain and explore the life of Tientsin Indian Sikhs.
