Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
vu kham » vu khanh
va hanh » van hanh, va thanh, va danh
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, ve cai
va cam » va cham, va cac, va cao
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: su sac ky nang x hoi. hieu ((((ve cam) OR (va cam))) or (vu kham)) duc va hanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang x hoi. hieu ((((ve cam) OR (va cam))) OR (vu kham)) duc va hanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. hieu ((((ve cam) OR (va cam))) or (vu kham)) duc va hanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: su sac ky nang x hoi. hieu ((((ve cam) OR (va cam))) or (vu kham)) duc va hanh dai cua te*.
