Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
truc ban » thuc ban, truc dan, truc van
tuc van » thuc van, truc van, tuc va
vi cua » vai cua, di cua
su sac » su sach, su cac, su xac
sac ky » cac ky, sai ky
ve cam » ve cham, va cam, ve cai
ve cac » va cac, vien cac
x hoi » xa hoi, o hoi, x ho

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. hieu ((ve cam) OR (ve cac)) ((tuc van) or (truc ban)) thanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang x hoi. hieu ((ve cam) OR (ve cac)) ((tuc van) OR (truc ban)) thanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang x hoi. hieu ((ve cam) OR (ve cac)) ((tuc van) or (truc ban)) thanh vi cua triet*".
