Perhaps you should try some spelling variations:

va kinh » va tinh, qua kinh
hieu va » lieu va, hieu qua
cam tuc » cam xuc, cam tu, nam thuc
va dinh » van dinh, va tinh, vu dinh
di cuu » di cau, di cua, dinh cuu
vu sac » vu sach, vu san, va sac
sac ky » cac ky, sai ky
va cam » va cham, va cac, va cao
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky nang x hoi. hieu va cam tuc ((va dinh) OR (va kinh)) ((di cuu) or (diem cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky nang x hoi. hieu va cam tuc ((va dinh) OR (va kinh)) ((di cuu) OR (diem cau)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky nang x hoi. hieu va cam tuc ((va dinh) OR (va kinh)) ((di cuu) or (diem cau)) tre*".
