Perhaps you should try some spelling variations:
thanh tai » thanh hai, thanh toan, doanh tai
va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
tai cuu » tai cuc, tai buu, tai cua
cuu tre » cua tre, cau tren, cau treo
ly hang » ly quang
ly hanh » ly anh, lu hanh, luu hanh
tuc va » thuc va, truc va, tuc xa
ve cam » ve cham, ve cac, va cam

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 ((ly hanh) OR (ly hang)) xa hoi. hieu ((ve cam) or (va cac)) tuc va thanh tai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ly hanh) OR (ly hang)) xa hoi. hieu ((ve cam) OR (va cac)) tuc va thanh tai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ly hanh) OR (ly hang)) xa hoi. hieu ((ve cam) or (va cac)) tuc va thanh tai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((ly hanh) OR (ly hang)) xa hoi. hieu ((ve cam) or (va cac)) tuc va thanh tai cuu tre*.
