Perhaps you should try some spelling variations:
vu triet » su triet, ve triet, tu triet
va triet » va thiet, va trien, ve triet
sanh ky » sang ky, nganh ky, thanh ky
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
xa hanh » xa thanh, xa khanh, va hanh
ve cam » ve cham, ve cac, va cam
kem » kiem

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

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