Perhaps you should try some spelling variations:
phap che » han che
lang van » dang van, tang van, hoang van
ban quan » van quan
phap thu » phap thuc, phap tu
dan quan » van quan, dan luan, dang quang
toc sac » toc sach, toc san, hoc sach
tai cua » thai cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
van hoc » van hoa
o lang » hoa lang, hoi lang

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: toc sac o lang van hoc. hieu ve ((phap thu) OR (phap che)) ((dan quan) OR (ban quan)) tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sac o lang van hoc. hieu ve ((phap thu) OR (phap che)) ((dan quan) or (ban quan)) tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sac o lang van hoc. hieu ve ((phap thu) OR (phap che)) ((dan quan) or (ban quan)) tai cua tre*.
