Perhaps you should try some spelling variations:
nang duy » nang du, nang dua, nang quy
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
truc va » thuc va, thuc vat, trung va
va nang » van nang, da nang, cam nang
duy cua » day cua, dung cua
y nang » ky nang, ly nang, v nang
ve cai » ve cac, ve tai, ve cau
va cai » va cac, va bai, va dai
va cam » va cham, va cac, va cao
cua te » cua tu

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: tu sach y nang xa hoi. hieu ((((ve cai) OR (va cai))) OR (va cam)) truc va nang duy cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang xa hoi. hieu ((((ve cai) or (va cai))) or (va cam)) truc va nang duy cua te*.
