Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
phat xuc » chat xuc, phat xuat, phat huy
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
phap xu » phap tu, phap thu, phap ngu
tu cach » tu cac
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
di cua » dai cua, doi cua, de cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (thuat sach)) ky nang xa hoi. hieu va ((phat xuc) OR (phap xu)) va hanh di cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (thuat sach)) ky nang xa hoi. hieu va ((phat xuc) OR (phap xu)) va hanh di cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (thuat sach)) ky nang xa hoi. hieu va ((phat xuc) OR (phap xu)) va hanh di cua tre*".
