Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cua tre » cua te, cuu tre, cua triet
vai cua » dai cua, hai cua, lai cua
tu sach » thu sach, su sach, te sach
ky lang » ky nang, ky dang, ky tang

thuc va » thuc vat, thuc dan, thuc day
tu sac » tu cac, tu san, tu bac
luc va » duc va, tuc va, loc va
ha hoi » hoa hoi, ha noi, xa hoi
va dao » ca dao

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 ha hoi. lieu va dao ((luc va) or (thuc va)) hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sac) OR (tu sach)) ky lang ha hoi. lieu va dao ((luc va) OR (thuc va)) hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu sach)) ky lang ha hoi. lieu va dao ((luc va) or (thuc va)) hanh vai cua tre*".
