Perhaps you should try some spelling variations:
van hanh » van thanh, ban hanh, van anh
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
dang ha » dung ha, lang ha, tang ha
dong ha » dong hoa, dong va, dong hoc
xuc van » duc van, luc van, xuc ban
tu sac » tu sach, tu cac, tu san
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
cua tu » cua tuc, cua su, cua cu

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

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