Perhaps you should try some spelling variations:
yang liang » yan liang, peng liang, yang guang
wang liang » wang yang
yang yang » wang yang, wang yan
heat gain » health gain, health gains, wheat grains
tae heat » tube heat, a heat, lag heat
hong hai » shang hai, zhong tai, dang hai
yang li » yang lin, yang xi, yang yi

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang liang) or (wang liang))) or (yang yang)) tae heat gain ((yang di) or (yang li)) hong hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang liang) OR (wang liang))) OR (yang yang)) tae heat gain ((yang di) OR (yang li)) hong hai ;.
• Adding a wildcard symbol may retrieve word variants: ((((yang liang) or (wang liang))) or (yang yang)) tae heat gain ((yang di) or (yang li)) hong hai ;*.
