Perhaps you should try some spelling variations:
deng xiaoyang » deng xiaoping, tang xiaoyang
tang chia » tan chia, hang china, wang chi
tang chun » wang chun, tung chung, kang chen
yang jing » wang jing, yang jin, huang jing
jing fang » jia fang, jin kang, weng fang
fang hai » dang hai, shang hai, eang hay

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "deng xiaoyang ((tang chia) OR (tang chun)) du yang jing fang hai ;~".
• Adding a wildcard symbol may retrieve word variants: deng xiaoyang ((tang chia) OR (tang chun)) du yang jing fang hai ;*.
