Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
van thanh » ban thanh, van tuan
thanh le » thinh le, thanh ve, thanh de
cua tre » cua te, cuu tre, dua tren
duc van » duc va, duc tan, duc manh
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
ve cam » ve cac, va cam, ve cai

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) duc van thanh le ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) duc van thanh le ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. hieu ((ve cam) OR (ve cham)) duc van thanh le ((cua tre) or (cua triet))*".
