Perhaps you should try some spelling variations:
van sinh » van minh, va sinh, van dinh
sinh dai » sinh thai, si dai, sinh vat
ve cham » va cham, ve chat, vu cham
duc van » duc va, duc tan, duc manh
tu ban » thu ban, te ban
ban ky » van ky, dan ky
ve cam » va cam, ve cai, ve cau
ve cac » va cac, vien cac
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: tu ban ky nang x hoi. hieu ((((ve cam) OR (ve cham))) or (ve cac)) duc van sinh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ban ky nang x hoi. hieu ((((ve cam) OR (ve cham))) OR (ve cac)) duc van sinh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ban ky nang x hoi. hieu ((((ve cam) OR (ve cham))) or (ve cac)) duc van sinh dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu ban ky nang x hoi. hieu ((((ve cam) OR (ve cham))) or (ve cac)) duc van sinh dai cua te*.
