Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, pham duc
nang co » nang doc, nang noi, nang hoc
hieu ve » hieu va, hieu van
va hanh » van hanh, va thanh, va danh
luu tre » luu tru, cuu tre, luy tre
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
vi luu » vi lua

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 ky ((nang co) OR (nang cao)) hoc. hieu ve ((cham xuc) or (cham soc)) va hanh vi luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((nang co) OR (nang cao)) hoc. hieu ve ((cham xuc) OR (cham soc)) va hanh vi luu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((nang co) OR (nang cao)) hoc. hieu ve ((cham xuc) or (cham soc)) va hanh vi luu tre*".
