Perhaps you should try some spelling variations:
seung yeon » seung joon, seung won, seung youn
jeong yeon » jeong hyeok, jeang yean, jeong dahyeon
wang ying » wang yang, wang yong, wang jing
ying yang » yang yang, yin yang, ying chang
yang api » yang dali, yang di, yang jui
api test » ai test, i test, ii test
test kaw » test a, test kit, test awt
kaw min » kyaw min, kan min, law main

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ying yang api test kaw min ((jeong yeon) OR (seung yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ying yang api test kaw min ((jeong yeon) OR (seung yeon)) ;*.
