Perhaps you should try some spelling variations:
jing fang » jia fang, jin kang, weng fang
david ian » david a, david n
yang iii » klang iii, yang zili, zwang iii
reform i » reform _, reform a, reform 1
yang li » yang lin, yang di, yang xi
ian hai » dang hai
form i » form _, form a

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

• If you are trying to use Boolean operators, they must be ALL CAPS: jing fang ((yang iii) OR (yang li)) ((form i) OR (reform i)) david ian hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "jing fang ((yang iii) or (yang li)) ((form i) OR (reform i)) david ian hai ;~".
• Adding a wildcard symbol may retrieve word variants: jing fang ((yang iii) or (yang li)) ((form i) OR (reform i)) david ian hai ;*.
