Perhaps you should try some spelling variations:
vien dai » hien dai
hanh dai » hanh tai, hanh dao, vanh dai
vien cac » vien bach, vien da, gian cac
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
cua duc » cua nuoc, cua quoc
xuc van » duc van, luc van, vuc van
cua tuc » cua tu, cua thuoc, luat tuc
sach ly » sach y, sach lo, sach ty
nang xa » nang x, lang xa, nang ma
ly nang » ky nang, ly hang, ly vang

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: te sach ly nang xa hoi. hieu ((vien cac) OR (vien dai)) xuc van hanh dai ((cua duc) OR (cua tuc))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang xa hoi. hieu ((vien cac) OR (vien dai)) xuc van hanh dai ((cua duc) or (cua tuc))~".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang xa hoi. hieu ((vien cac) OR (vien dai)) xuc van hanh dai ((cua duc) or (cua tuc))*.
