Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
nam trung » nam trong, tai trung, ba trung
nam truc » nam truoc, nam thuc, nam thuoc
thanh vi » hanh vi, thanh va, thanh ve
su sach » so sach, vu sach
nang xa » lang xa, nang ma, mang xa
cuu tre » cua tre, cau tren, cau treo
vi cuu » vi luu, vinh cuu

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 y ((nang xa) OR (nang x)) hoi. lieu va ((nam truc) or (nam trung)) van thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((nang xa) OR (nang x)) hoi. lieu va ((nam truc) OR (nam trung)) van thanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((nang xa) OR (nang x)) hoi. lieu va ((nam truc) or (nam trung)) van thanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: su sach y ((nang xa) OR (nang x)) hoi. lieu va ((nam truc) or (nam trung)) van thanh vi cuu tre*.
