Perhaps you should try some spelling variations:
tran trong » gian trong, quan trong, tran hong
nhung thoi » nhung thi, phung thi, nhung loi
quan thanh » van thanh
chung chi » thuong chi, chung cu, chung vi
biet tran » bien tran, viet tran, viet trang
ban thanh » ban hanh, ban hang
que van » qua van, quy van, quyet van

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: ((nhung thoi) OR (chung chi)) que van. biet tran trong ((quan thanh) OR (ban thanh))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung thoi) or (chung chi)) que van. biet tran trong ((quan thanh) OR (ban thanh))~".
• Adding a wildcard symbol may retrieve word variants: ((nhung thoi) or (chung chi)) que van. biet tran trong ((quan thanh) OR (ban thanh))*.
