Perhaps you should try some spelling variations:
tay lang » tay tang, tay quang, tham lang
tai lang » tai cong, thi lan, tai san
hieu van » hieu va, thien van, lieu va
cam truc » nam truc, lam truoc, nam truoc
van hanh » van thanh, ban hanh, van anh
te sach » toc sach
cua tuc » cua duc, cua tu, cua thuoc
vi cua » vai cua, di cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((tay lang) OR (tai lang)) xa hoi. hieu van ((cam truc) OR (cau truc)) van hanh vi cua tuc~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tay lang) OR (tai lang)) xa hoi. hieu van ((cam truc) or (cau truc)) van hanh vi cua tuc~".
• Adding a wildcard symbol may retrieve word variants: te sach ((tay lang) OR (tai lang)) xa hoi. hieu van ((cam truc) or (cau truc)) van hanh vi cua tuc*.
