Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thien van » thi van
hanh lai » hanh lam, hanh tai, thanh lap
van hanh » van thanh, ban hanh, van anh
lai cua » dai cua, hai cua, lai chau
cac xuc » cac nuoc, chat xuc, cac cuoc
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
nang ma » tang ma, sang ma, nang cao
nang xa » nang x, lang xa, mang xa

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 ky ((nang xa) OR (nang ma)) hoi. thien van ((cac xuc) or (cam xuc)) van hanh lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((nang xa) OR (nang ma)) hoi. thien van ((cac xuc) OR (cam xuc)) van hanh lai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((nang xa) OR (nang ma)) hoi. thien van ((cac xuc) or (cam xuc)) van hanh lai cua triet*".
