Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
va cham » va chat, va tham
tai cua » thai cua, tai cuc, tri cua
tu sach » thu sach, su sach, te sach
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va dung » van dung, va duong, vat dung
tuc va » thuc va, truc va, tuc xa
tu sac » tu cac, tu san, tu bac
va cam » va cac, va cao, va cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu ((va cam) or (va cham)) tuc va dung tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky lang xa hoi. hieu ((va cam) OR (va cham)) tuc va dung tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky lang xa hoi. hieu ((va cam) or (va cham)) tuc va dung tai cua tre*".
