Perhaps you should try some spelling variations:
shang hai » shang kai, dang hai, chang ha
mang yul » sang yu, tang yun, yang yue
wang yue » wong yue, wang hua, wang yan
sang yoo » sang yu
yang lin » yang jin, wang lin, yang li
wan yin » fan ying, ran ying, tan ying
yang yi » yang di, yang xi, 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: wan yin ((((mang yul) OR (wang yue))) or (sang yoo)) chen ((yang lin) or (yang yi)) shang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yin ((((mang yul) OR (wang yue))) OR (sang yoo)) chen ((yang lin) OR (yang yi)) shang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yin ((((mang yul) OR (wang yue))) or (sang yoo)) chen ((yang lin) or (yang yi)) shang hai ;*".
