Perhaps you should try some spelling variations:
hanh tri » thanh tri, hanh tai, hanh trinh
van hanh » van thanh, ban hanh, van anh
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang va
cua tre » cuu tre, cua triet, dua tren
dang ha » dong ha, dung ha, lang ha
xuc van » duc van, luc van, vuc van
su tai » su thi, tu tai
ve cam » ve cham, ve cac, va cam
tai ky » thai ky, trai ky, sai ky
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: su tai ky ((dang xa) OR (dang ha)) hoi. hieu ve cam xuc van hanh tri ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su tai ky ((dang xa) OR (dang ha)) hoi. hieu ve cam xuc van hanh tri ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su tai ky ((dang xa) OR (dang ha)) hoi. hieu ve cam xuc van hanh tri ((cua tre) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: su tai ky ((dang xa) OR (dang ha)) hoi. hieu ve cam xuc van hanh tri ((cua tre) or (cua te))*.
