Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
nang ma » tang ma, sang ma, nang cao
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
va cuu » va chu, va huu
va cau » van cau, va cac, va dau

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ky nang ma hoa. hieu ve cham xuc ((van hanh) or (ban hanh)) ((va cuu) OR (va cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ky nang ma hoa. hieu ve cham xuc ((van hanh) OR (ban hanh)) ((va cuu) OR (va cau)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang ma hoa. hieu ve cham xuc ((van hanh) or (ban hanh)) ((va cuu) OR (va cau)) tre*".
