Perhaps you should try some spelling variations:
hanh di » hanh vi, hanh de, hang di
va hanh » van hanh, va thanh, va danh
va cao » va cac, va co, va dao
di cua » dai cua, doi cua, de cua
ve cao » ve bao, ve cac, ve co
sac ky » cac ky
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sac ky) or (sai ky)) nang x hoi. hieu ((ve cao) OR (va cao)) duc va hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sac ky) OR (sai ky)) nang x hoi. hieu ((ve cao) OR (va cao)) duc va hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sac ky) or (sai ky)) nang x hoi. hieu ((ve cao) OR (va cao)) duc va hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sac ky) or (sai ky)) nang x hoi. hieu ((ve cao) OR (va cao)) duc va hanh di cua te*.
