Perhaps you should try some spelling variations:
quyen vang » quyet van, huyen van, duyen dang
quyen van » quyet van, huyen van, nguyen van
thien cac » thien cau, thieu cac, trien cac
hien giam » khien giam, nien giam, thien giap
nhung su » nhung quy, nhung cau, nhung mau
hien cac » vien cac, hieu cac, dien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: nhung su ((quyen vang) OR (quyen van)). biet the ((((hien cac) or (thien cac))) or (hien giam)) xuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nhung su ((quyen vang) OR (quyen van)). biet the ((((hien cac) OR (thien cac))) OR (hien giam)) xuc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nhung su ((quyen vang) OR (quyen van)). biet the ((((hien cac) or (thien cac))) or (hien giam)) xuc".
• Adding a wildcard symbol may retrieve word variants: nhung su ((quyen vang) OR (quyen van)). biet the ((((hien cac) or (thien cac))) or (hien giam)) xuc*.
