Perhaps you should try some spelling variations:
dau tren » dau tien, dat tren, dau tieng
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
truc va » thuc va, thuc vat, trung va
hanh bi » hanh vi, thanh bai, khanh bui
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
xuc va » duc va, tuc va, luc va

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 ky) OR (sac ky)) nang xa hoi. hieu ve cam ((xuc va) or (truc va)) hanh bi dau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cam ((xuc va) OR (truc va)) hanh bi dau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cam ((xuc va) or (truc va)) hanh bi dau tren".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve cam ((xuc va) or (truc va)) hanh bi dau tren*.
