Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh lai » thanh hai, thanh lap, thanh loi
hay thanh » ha thanh, hai thanh, day thanh
chat xuc » chat huu, cam xuc, chao xu
su sach » so sach, vu sach
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
sang ma » tang ma, sang tao, mang may
nang ma » tang ma, nang cao, mang may
su viet » so viet

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

• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang ma) OR (sang ma)) hoi. hieu ve chat xuc hay thanh lai ((cua triet) OR (su viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang ma) OR (sang ma)) hoi. hieu ve chat xuc hay thanh lai ((cua triet) or (su viet))~".
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang ma) OR (sang ma)) hoi. hieu ve chat xuc hay thanh lai ((cua triet) or (su viet))*.
