Perhaps you should try some spelling variations:
rent line » front line
zhong tai » hong tan, hong hai
zhong zhi » zhang zhi, hong ghi
yang can » yang fan, yang yang, yang jin
oil rent » oil rents, oil trend, oil real
wong yue » wang yue, hong yu
line li » line hi, line log, line pll

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yang can) OR (yang dean)) oil rent line li ((((zhong tai) or (zhong zhi))) or (wong yue)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yang can) OR (yang dean)) oil rent line li ((((zhong tai) OR (zhong zhi))) OR (wong yue)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang can) OR (yang dean)) oil rent line li ((((zhong tai) or (zhong zhi))) or (wong yue)) ;*".
