Perhaps you should try some spelling variations:
thuc dan » thuc hanh, hoc dan, thuc vat
dan hanh » dang hanh, dan khanh, dan thanh
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
van dau » van dao, phan dau
van hac » van hoc, van hai, van chat
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
van ha » van hoa, van chat, van hanh

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang xa hoi. hieu ((van dau) or (((van hac) OR (van ha)))) thuc dan hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ((van dau) OR (((van hac) OR (van ha)))) thuc dan hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ((van dau) or (((van hac) OR (van ha)))) thuc dan hanh vai cua tre*".
