Perhaps you should try some spelling variations:

thanh lap » thanh san, phan lap, thanh hai
thien van » thi van
hanh lai » hanh lam, hanh tai, thanh loi
chat duc » chat xuc, chat doc, chet duoc
van chat » cao chat
lang xa » lang ha, dang xay, lang van
tu sach » thu sach, su sach, te sach

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 y ((lang xa) or (nang x)) hoi. thien van chat duc va ((hanh lai) OR (thanh lap)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((lang xa) OR (nang x)) hoi. thien van chat duc va ((hanh lai) OR (thanh lap)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((lang xa) or (nang x)) hoi. thien van chat duc va ((hanh lai) OR (thanh lap)) cua triet*".
