Perhaps you should try some spelling variations:
tay lang » tai lang, tay quang, tham lang
ban hanh » ban hang
tay tang » tay trung, tay quang, tay tieng
van hanh » van thanh, van anh, van ban
te sach » toc sach
cao hoc » co hoc, cho hoc, chat hoc
hieu ke » hieu kem, chieu ke, hieu ky
ke cao » ke cau, ke co, te cao
ha hoi » hoa hoi, ha noi, xa hoi
di cua » dai cua, doi cua, de cua
cua te » cua tu

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 (tay tang)) ha hoi. hieu ke cao hoc ((van hanh) OR (ban hanh)) di cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((tay lang) OR (tay tang)) ha hoi. hieu ke cao hoc ((van hanh) or (ban hanh)) di cua te~".
• Adding a wildcard symbol may retrieve word variants: te sach ((tay lang) OR (tay tang)) ha hoi. hieu ke cao hoc ((van hanh) or (ban hanh)) di cua te*.
