Perhaps you should try some spelling variations:
cach thuc » anh thuc, cac thu
qua cach » qua cac, quan sach, quat canh
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
va hanh » van hanh, va thanh, va danh
luu tre » luu tru, luy tre
cuu tre » cua tre, cau tren, cau treo
su xac » pu xac
su cac » tu cac, su cao, su can

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((su xac) or (su cac)) ky nang xa hoi. hieu qua cach thuc va hanh vi ((luu tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su xac) OR (su cac)) ky nang xa hoi. hieu qua cach thuc va hanh vi ((luu tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su xac) or (su cac)) ky nang xa hoi. hieu qua cach thuc va hanh vi ((luu tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: ((su xac) or (su cac)) ky nang xa hoi. hieu qua cach thuc va hanh vi ((luu tre) OR (cuu tre))*.
