Perhaps you should try some spelling variations:
ve triet » va trien, su triet
van hanh » van thanh, ban hanh, van anh
va thanh » gia thanh, ban thanh, va tinh
nang ha » nang hai, nang han, nang hoa
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
ha hoi » hoa hoi, ha noi, xa hoi
ve cac » va cac, vien cac
ke ve » ke va, ke he, de ve

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang ha hoi. hieu ((ve cam) OR (ve cac)) xuc ((va thanh) or (van hanh)) ke ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ha hoi. hieu ((ve cam) OR (ve cac)) xuc ((va thanh) OR (van hanh)) ke ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ha hoi. hieu ((ve cam) OR (ve cac)) xuc ((va thanh) or (van hanh)) ke ve triet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang ha hoi. hieu ((ve cam) OR (ve cac)) xuc ((va thanh) or (van hanh)) ke ve triet*.
