Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
hanh cat » hanh cac, hanh luat, nhanh cay
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cat cua » chat cua, ca cua, mat cua
cua tre » cua te, cuu tre, cua triet
ve cam » ve cham, ve cac, va cam
luc va » loc va
tuc va » thuc va, truc va, tuc xa

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 ky nang xa hoi. hieu ve cam ((((luc va) OR (tuc va))) or (duc va)) hanh cat cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky nang xa hoi. hieu ve cam ((((luc va) OR (tuc va))) OR (duc va)) hanh cat cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky nang xa hoi. hieu ve cam ((((luc va) OR (tuc va))) or (duc va)) hanh cat cua tre*".
