Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
te sach » toc sach
vai cuu » vai cua
va hanh » van hanh, va thanh, va danh
cuu tre » cua tre, cau tren, cau treo
tu nang » tru nang, tu nong, tu nano
tuc va » thuc va, truc va, tuc xa
ve co » vo co, va co, ke co
de co » ke co

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((tu nang) or (truc nano)) xa hoi. hieu ((ve co) OR (de co)) tuc va hanh vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tu nang) OR (truc nano)) xa hoi. hieu ((ve co) OR (de co)) tuc va hanh vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tu nang) or (truc nano)) xa hoi. hieu ((ve co) OR (de co)) tuc va hanh vai cuu tre*".
