Perhaps you should try some spelling variations:
cau tren » dau tren, ca tren, cau treo
hanh lai » hanh lam, hanh tai, thanh lap
te sach » toc sach
sach ty » sach y, sach tu, sach thu
va hanh » van hanh, va thanh, va danh
xang xa » lang xa, mang xa, ang xa
cu tren » tu tren, dua tren
ve cac » va cac, vien cac
tuc va » thuc va, truc va, tuc xa
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 xang xa hoi. hieu ((ve cam) or (ve cac)) tuc va hanh lai ((cau tren) OR (cu tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang xa hoi. hieu ((ve cam) OR (ve cac)) tuc va hanh lai ((cau tren) OR (cu tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. hieu ((ve cam) or (ve cac)) tuc va hanh lai ((cau tren) OR (cu tren))*".
