Perhaps you should try some spelling variations:
hanh lai » hanh tai, thanh lap, thanh loi
hanh lam » thanh lap, hanh kem, hanh va
cau tren » cu tren, dau tren, ca tren
te sach » toc sach
sach ty » sach y, sach tu, sach thu
xang xa » lang xa, mang xa, ang xa
truc va » thuc va, thuc vat, trung va
ve cam » ve cham, ve cac, va cam
hien » bien, vien, tien

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