you liang » you xian, you liangzhi
shang hai » shang kai, dang hai, chang ha
han heat » a heat, can hear, lag heat
yang jui » yang judy, yang xi, yang yi
man han » man hat, man can, man kann
kann » ann

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

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