Perhaps you should try some spelling variations:
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
leong yeon » jeong yeon, seung yeon
min leong » min jeong, mun leong, kin keong
yang jui » yang judy, yang di, yang xi
test kan » test kit, test ke
test a » test _, test 4, test 5

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 yang jui ((test kan) OR (test a)) min leong yeon ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang yang jui ((test kan) OR (test a)) min leong yeon ;*".
