Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
te sach » toc sach
lai cuu » lai cua, lai chau, lai cuoc
va hanh » van hanh, va thanh, va danh
truc va » thuc va, thuc vat, trung va
cuu tre » cua tre, cau tren, cau treo
ty hang » ly hang, ty xang, thi hang
ty lang » tay lang, ty xang, tu lang
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cai

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 ((ty lang) OR (ty hang)) xa hoi. hieu ((ve cam) or (ve cac)) truc va hanh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty lang) OR (ty hang)) xa hoi. hieu ((ve cam) OR (ve cac)) truc va hanh lai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty lang) OR (ty hang)) xa hoi. hieu ((ve cam) or (ve cac)) truc va hanh lai cuu tre*".
