What next? There are various ways you can either follow up and find out more about the details you have found, or look elsewhere if your search has not been successful. One source is our related Historical Photographs of China site which contains nearly 20,000 digitised historic photographs most of which came to the project from China families.
Residential directories: this page here on China Families provides links to online copies of historical residential and business directories published between 1842 and the 1930s.
