Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
sach thu » sach thue, sach thieu, sach tham
thu nang » thi nang, thu hang, thu bang
thanh vi » thanh va, thanh ve, nhanh vi
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
ve cac » va cac, vien cac
x hoi » xa hoi, o hoi, 5 hoi

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach thu nang ((x hoi) or (x ho)). hieu ve cac xuc van ((thanh vi) OR (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach thu nang ((x hoi) OR (x ho)). hieu ve cac xuc van ((thanh vi) OR (hanh vi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach thu nang ((x hoi) or (x ho)). hieu ve cac xuc van ((thanh vi) OR (hanh vi)) cua triet*".
