Perhaps you should try some spelling variations:
day tieng » dau tieng, va tieng, ban tieng
sach ty » sach y, sach tu, sach thu
hanh bi » hanh vi, thanh bai, khanh bui
truc va » thuc va, thuc vat, trung va
te sach » toc sach
hieu va » lieu va
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
tuc va » thuc va, tuc xa, duc va
bi day » bi dau, bo day

You may be able to get more results by adjusting your search query.

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