Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yan » yang yang, wang yan, yang fan
yan hua » ya hua, wang hua, tuan hua
tan hua » tuan hua, wang hua, tan chia
yang xi » yang di, yang yi, yang jui
hong yu » wong yue
shang » zhang, chang, sheng

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yan) or (wang yang))g ((yan hua) OR (tan hua)) rest ((shang jin) or (yang xi)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yan) OR (wang yang))g ((yan hua) OR (tan hua)) rest ((shang jin) OR (yang xi)) hong yu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yan) or (wang yang))g ((yan hua) OR (tan hua)) rest ((shang jin) or (yang xi)) hong yu ;".
• Adding a wildcard symbol may retrieve word variants: ((yang yan) or (wang yang))g ((yan hua) OR (tan hua)) rest ((shang jin) or (yang xi)) hong yu ;*.
