Perhaps you should try some spelling variations:
tinh doi » trinh doc, trinh do, tinh hoc
doi cua » dai cua, hoi cua
te ban » te bao
loc va » luc va
ve cac » va cac, vien cac
ban ky » van ky, dan ky
ve cam » ve cham, va cam, ve cai
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: te ban ky nang x hoi. hieu ((ve cam) or (ve cac)) ((loc va) OR (hoc va)) tinh doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ban ky nang x hoi. hieu ((ve cam) OR (ve cac)) ((loc va) OR (hoc va)) tinh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ban ky nang x hoi. hieu ((ve cam) or (ve cac)) ((loc va) OR (hoc va)) tinh doi cua te".
• Adding a wildcard symbol may retrieve word variants: te ban ky nang x hoi. hieu ((ve cam) or (ve cac)) ((loc va) OR (hoc va)) tinh doi cua te*.
