Perhaps you should try some spelling variations:
tuyen tai » truyen tai, tuyen tap, nguyen tai
xuyen tai » xuyen tac, nguyen tai, truyen tai
tran dang » tran quang, tran hoang, tranh hang
dang cong » dung cong
cac thoi » cac toi, cac hop, cac tro
ve ly » ve ky, ve y, de ly
ve li » ve ki

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: ((tuyen tai) OR (xuyen tai)) cac thoi đe co ban ((ve ly) OR (ve li)) tran dang cong~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tuyen tai) or (xuyen tai)) cac thoi đe co ban ((ve ly) OR (ve li)) tran dang cong~".
• Adding a wildcard symbol may retrieve word variants: ((tuyen tai) or (xuyen tai)) cac thoi đe co ban ((ve ly) OR (ve li)) tran dang cong*.
