Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
dang thi » hoang thi, dang khoi
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
duc van » duc va, duc tan, duc manh
anh thi » anh tho, dinh thi, anh thuc
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam
x hoi » o hoi, x ho, 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 sac ky nang ((x hoi) OR (xa hoi)). hieu ve cam duc van ((anh thi) or (dang thi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang ((x hoi) OR (xa hoi)). hieu ve cam duc van ((anh thi) OR (dang thi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang ((x hoi) OR (xa hoi)). hieu ve cam duc van ((anh thi) or (dang thi)) cua triet*".
