Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
dung sai » dung tai, dung va, dung dat
va cham » va chat, va tham
sai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
sach ly » sach y, sach lo, sach ty
ve cham » ve chat, vu cham, ve chim
ly nang » ky nang, ly hang, ly vang
xuc va » tuc va, luc va, xac va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thuat sach ly nang x hoi. hieu ((ve cham) or (va cham)) ((xuc va) OR (duc va)) dung sai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ly nang x hoi. hieu ((ve cham) OR (va cham)) ((xuc va) OR (duc va)) dung sai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ly nang x hoi. hieu ((ve cham) or (va cham)) ((xuc va) OR (duc va)) dung sai cua tre*".
