Perhaps you should try some spelling variations:
loai tren » la tren, thai tren
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
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
va cham » va chat
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
va tham » van tham, va thanh, va thuat

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky dang xa hoi. lieu ((va cham) OR (va tham)) xuc van thanh vi ((cau tren) or (loai tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xa hoi. lieu ((va cham) OR (va tham)) xuc van thanh vi ((cau tren) OR (loai tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky dang xa hoi. lieu ((va cham) OR (va tham)) xuc van thanh vi ((cau tren) or (loai tren))*".
