Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
va triet » va thiet, va trien, ve triet
nang xa » nang x, lang xa, nang ma
xuc van » duc van, luc van, vuc van
hanh de » hanh ve, hanh kem
sach v » sach va, sach y, sach vay
sach 2 » sach y
de va » de van, te va, ke va

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuoc ((sach v) OR (sach 2)) nang xa hoi. ((hieu qua) or (lieu va)) cam xuc van hanh de va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc ((sach v) OR (sach 2)) nang xa hoi. ((hieu qua) OR (lieu va)) cam xuc van hanh de va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc ((sach v) OR (sach 2)) nang xa hoi. ((hieu qua) or (lieu va)) cam xuc van hanh de va triet".
• Adding a wildcard symbol may retrieve word variants: thuoc ((sach v) OR (sach 2)) nang xa hoi. ((hieu qua) or (lieu va)) cam xuc van hanh de va triet*.
