Perhaps you should try some spelling variations:
nganh ky » nganh y, nganh xay, nganh co
van hanh » van thanh, van anh, van ban
ban hanh » ban hang
hanh ky » hanh kem
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
vi cua » vai cua, di cua
cua te » cua tu

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

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