Perhaps you should try some spelling variations:
quyen tap » tuyen tap, luyen tap, huyen tam
quyen cap » quyen cach, huyen cao, quyen con
thuy dung » thuy duong, thuoc dung, huy duong
thu dung » thuc dung, thu dang, thu dong
cac khu » cac thu, cac khoi, cac kieu
ban ve » ban va
ve ly » ve ky, ve li, ve y

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((quyen tap) or (quyen cap)) cac khu đe co ban ve ly ((thu dung) OR (thuy dung)) cong~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((quyen tap) OR (quyen cap)) cac khu đe co ban ve ly ((thu dung) OR (thuy dung)) cong.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((quyen tap) or (quyen cap)) cac khu đe co ban ve ly ((thu dung) OR (thuy dung)) cong".
• Adding a wildcard symbol may retrieve word variants: ((quyen tap) or (quyen cap)) cac khu đe co ban ve ly ((thu dung) OR (thuy dung)) cong*.
