Perhaps you should try some spelling variations:
van sinh » van minh, va sinh, van dinh
sinh dai » sinh thai, si dai, sinh vat
duc van » duc va, duc tan, duc manh
tu dan » tuc dan, tu ban, cu dan
dan ky » van ky
ve cam » ve cham, va cam, ve cai
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: tu dan ky nang x hoi. hieu ((ve cam) OR (ve cac)) duc van sinh dai cua te~.
• Adding a wildcard symbol may retrieve word variants: tu dan ky nang x hoi. hieu ((ve cam) or (ve cac)) duc van sinh dai cua te*.
