Perhaps you should try some spelling variations:
va triet » va thiet, va trien, ve triet
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
nang xa » nang x, lang xa, nang ma
vai va » mai va, dai va, hai va
lo van » le van, vo van, so van
sac ky » cac ky
ve cac » vien cac

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) OR (sai ky)) nang xa hoi. hieu ((ve cac) OR (va cac)) lo van hanh vai va triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sac ky) OR (sai ky)) nang xa hoi. hieu ((ve cac) OR (va cac)) lo van hanh vai va triet".
• Adding a wildcard symbol may retrieve word variants: te ((sac ky) OR (sai ky)) nang xa hoi. hieu ((ve cac) OR (va cac)) lo van hanh vai va triet*.
