Perhaps you should try some spelling variations:
ve triet » va trien, su triet
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
sach ky » sach y, sach ty, sach kem
xuc van » duc van, luc van, vuc van
hang ki » hang di, hang ke, hoang kim
hang vi » hang va, hanh vi, hang di
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: thu ((sach ky) OR (sac ky)) lang xa hoi. hieu ve cam xuc van ((hang ki) or (hang vi)) ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) lang xa hoi. hieu ve cam xuc van ((hang ki) OR (hang vi)) ve triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sac ky)) lang xa hoi. hieu ve cam xuc van ((hang ki) or (hang vi)) ve triet*".
