Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, jeong dahyeon
seung yeon » seung joon, seung won, seung youn
wang kong » wang yong, wang hong, hong kong
kong hang » kong heng, kong hong, kong land
ii testi » i testi, ii test, ai test
law past » law part, law east, flow past
hang ii » zhang ii, anhang ii
flow » flows, low

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 kong hang ii testi ((flow model) OR (law past)) ((jeong yeon) OR (seung yeon)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kong hang ii testi ((flow model) or (law past)) ((jeong yeon) OR (seung yeon)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang kong hang ii testi ((flow model) or (law past)) ((jeong yeon) OR (seung yeon)) ;*.
