Perhaps you should try some spelling variations:
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
nang du » nang tu, nang luc, nang doc
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
du cua » duy cua, dau cua, dum cua
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 du cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. hieu ((((ve cai) OR (va cai))) or (va cam)) truc va nang du 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 du cua te*.
