Perhaps you should try some spelling variations:
nganh ky » nganh y, nganh xay, hanh ky
sanh ky » hanh ky, thanh ky, sang kyo
sang ky » sang kyo, dang ky, tang ky
cao hoi » cau hoi, co hoi, cao hoc
hieu ve » hieu va, hieu van
xuc cac » xuc tac, tuc cac, xuc cam
ve cam » ve cham, ve cac, va cam
ca cua » co cua
cua su » qua su

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: so ((((sanh ky) OR (sang ky))) or (nganh ky)) nang cao hoi. hieu ve cam xuc cac dan ca cua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((((sanh ky) OR (sang ky))) OR (nganh ky)) nang cao hoi. hieu ve cam xuc cac dan ca cua su.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((((sanh ky) OR (sang ky))) or (nganh ky)) nang cao hoi. hieu ve cam xuc cac dan ca cua su".
• Adding a wildcard symbol may retrieve word variants: so ((((sanh ky) OR (sang ky))) or (nganh ky)) nang cao hoi. hieu ve cam xuc cac dan ca cua su*.
