Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, seung yeon
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
hong yeon » dong myeon, hong seo, hong een
test kaw » test a, test kit, test awt
yang ai » yang di, yang xi, yang yi
ai test » api test, i test, ii test
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 yong yang ai test kaw min ((hong yeon) OR (jeong yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang ai test kaw min ((hong yeon) OR (jeong yeon)) ;*.
