Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
va danh » va dinh, va hanh, dia danh
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
va dan » ca dan, va dao, va dau
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: tu sac ky nang x hoi. hieu ve cam duc ((va danh) OR (va dan)) ((hoi cua) or (hoi chuc)) tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang x hoi. hieu ve cam duc ((va danh) OR (va dan)) ((hoi cua) OR (hoi chuc)) tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. hieu ve cam duc ((va danh) OR (va dan)) ((hoi cua) or (hoi chuc)) tu".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. hieu ve cam duc ((va danh) OR (va dan)) ((hoi cua) or (hoi chuc)) tu*.
