Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cau tren » cu tren, dau tren, ca tren
thanh vi » hanh vi, thanh va, thanh ve
xuc van » duc van, luc van, vuc van
sach ky » sach y, sach ty, sach kem
la tren » loai tren, dua tren, dat tren
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
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)) dang xa hoi. hieu ve cam xuc van thanh vi ((cau tren) or (la tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sac ky)) dang xa hoi. hieu ve cam xuc van thanh vi ((cau tren) OR (la tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sac ky)) dang xa hoi. hieu ve cam xuc van thanh vi ((cau tren) or (la tren))*".
