Perhaps you should try some spelling variations:
yang kang » yang yang, yang guang, yang liang
yan liang » yang liang, wang liang, you liang
zhong tai » hong tan, zhong zhi
hua gain » heat gain, run gain, hua ban
hong hai » shang hai, dang hai, hong tan
tae hua » tan hua, tuan hua
yang xi » yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang kang) or (yan liang)) tae hua gain ((yang di) or (yang xi)) ((hong hai) OR (zhong tai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang kang) OR (yan liang)) tae hua gain ((yang di) OR (yang xi)) ((hong hai) OR (zhong tai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang kang) or (yan liang)) tae hua gain ((yang di) or (yang xi)) ((hong hai) OR (zhong tai)) ;".
• Adding a wildcard symbol may retrieve word variants: ((yang kang) or (yan liang)) tae hua gain ((yang di) or (yang xi)) ((hong hai) OR (zhong tai)) ;*.
