vu kham » vu khanh
va hanh » van hanh, va thanh, va danh
su sac » su sach, su cac
su xac » pu xac, su cac
ve cam » ve cham, ve cac, va cam
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) OR (su xac)) ky nang x hoi. hieu ((ve 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) OR (su xac)) ky nang x hoi. hieu ((ve 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) OR (su xac)) ky nang x hoi. hieu ((ve cam) or (vu kham)) duc va hanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky nang x hoi. hieu ((ve cam) or (vu kham)) duc va hanh dai cua te*.
