Embarking on such photographic projects make me look for relevant snippets of history, social mores and art (for example, the occupation of Shanghai by the Japanese in the thirties, the Chinoiserie fad of the 18th century, fictional stories similar to that of Madam Butterfly et al). I also learned the aesthetic of the cheongsam (aka qi pao) in its various forms, and the beauty of Chinese calligraphy. I also scoured the internet for Chinese legends, poetry and songs/music that inspired the 2-3 minutes plots of my photo films; as I call these audio slideshows.
The patrician-looking (and rather taciturn) sadhu in the top photograph did tell me that he had a family, had held a managerial position in the Indian Railway from which he earned a pension (now paid to his wife), but had decided to detach himself from temporal life and was currently studying the Vedas. These are the oldest scriptures of Hinduism. He was the embodiment of a real sadhu who had really espoused the Vairāgya, and was far different from the "sadhus" I encountered on the ghats of Varanasi (below) almost 8 years later.
Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
