Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh tai
ban hanh » ban hang
cua tre » cua te, cuu tre, dua tren
xuc ban » duc ban, cuc ban, quoc ban
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
sach ty » sach y, sach tu, sach thu
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: su ((sac ky) or (sach ty)) dang xa hoi. hieu ve cam xuc ban hanh vai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (sach ty)) dang xa hoi. hieu ve cam xuc ban hanh vai ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) or (sach ty)) dang xa hoi. hieu ve cam xuc ban hanh vai ((cua tre) OR (cua triet))*".
