Perhaps you should try some spelling variations:
thien van » thi van
nang cau » nang cao, hang cau, nang dau
van nhan » van phan, van thanh, danh nhan
nhan luc » nang luc
thanh vi » thanh va, thanh ve, nhanh vi
su triet » su viet, su tien, ve triet
luc ban » duc ban, cuc ban, luc bat

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ky nang cau hoi. thien van nhan luc ban ((thanh vi) OR (hanh vi)) su triet~".
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang cau hoi. thien van nhan luc ban ((thanh vi) OR (hanh vi)) su triet*.
