Perhaps you should try some spelling variations:
cau theo » cau thi, cau tao
nang xa » nang x, lang xa, nang ma
va khai » van khai, va kha, va khi
va hanh » van hanh, va thanh, va danh
hanh ve » hanh vi, hanh va, hanh kem
sai ky » sac ky
xuc va » duc va, tuc va, luc va
ve cau » ke cau, va cau, ve cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sai ky) or (cac ky)) nang xa hoi. lieu ((va khai) or (va khao)) xuc va hanh ve cau theo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sai ky) OR (cac ky)) nang xa hoi. lieu ((va khai) OR (va khao)) xuc va hanh ve cau theo.
• Adding a wildcard symbol may retrieve word variants: su ((sai ky) or (cac ky)) nang xa hoi. lieu ((va khai) or (va khao)) xuc va hanh ve cau theo*.
