Perhaps you should try some spelling variations:
zhang min » zhang ming, zhang xin, chang min
gong gang » hong gang, gong qiang, gongs gong
tong shui » tong hui, cong shu, gong hui
hong shu » cong shu, wong shiu, hong seo
shu zhi » shi zhi, su zhi
hu zhi » su zhi
rent » rents
rest » west, best, test

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: gong gang ((hu zhi) OR (shu zhi)) (rent OR rest) zhang min ((hong shu) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gong gang ((hu zhi) or (shu zhi)) (rent or rest) zhang min ((hong shu) OR (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: gong gang ((hu zhi) or (shu zhi)) (rent or rest) zhang min ((hong shu) OR (tong shui)) ;*.
