Perhaps you should try some spelling variations:
yong zhang » yong phang, kong hang, yan zhang
jeong yeon » jeong hyeok, jeang yean, jeong dahyeon
seung yeon » seung joon, seung won, seung youn
wang yong » wang yang, wang hyoung, wang yan
zhang ii » zhang i, zhang li, zhang si
ii testi » i testi, ii test, ai test
law past » law part, law east, flow past

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong zhang ii testi ((new model) OR (law past)) ((jeong yeon) OR (seung yeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong zhang ii testi ((new model) or (law past)) ((jeong yeon) OR (seung yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong zhang ii testi ((new model) or (law past)) ((jeong yeon) OR (seung yeon)) ;*.
