Perhaps you should try some spelling variations:
wang liang » wang yang
liang kang » liang dan, liang tan, liang ying
kyung hwan » jung hwan
yang yang » wang yang, wang yan
han kyung » han kyul, han heung, jin kyung
kang ya » kang ca, wang yan, kong yam
yi yang » yin yang, yu yang, ying yang
yi gang » ii gang, i gang, li gang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang liang kang ya ((((yi yang) OR (yi gang))) or (yang yang)) han kyung hwan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang kang ya ((((yi yang) OR (yi gang))) OR (yang yang)) han kyung hwan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang kang ya ((((yi yang) OR (yi gang))) or (yang yang)) han kyung hwan ;*".
