Perhaps you should try some spelling variations:
thuoc phien » thuc hien, phuoc hien, thuat phien
dong thuoc » dung thuoc, dang thuoc, don thuoc
phien nam » phien ban, vien nam, mien nam
thai hien » thai phien, thi hien, thoi hien
danh tac » canh tac, danh bac, doanh tai
phan nam » pham nam, nhan nam, phan cam
hoc phan » hoc dan, hoc pho
tac dong » tac dung, tac trong, ha dong
hien nay » hien dai
hien nam » vien nam, mien nam, huyen nam
tac van » tac vang, cac van, tac va
van hoc » van hoa
tac xa » tac da

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: (( danh ((tac xa) OR (tuc xa)) thai hien nam ) OR ((( danh tac dong thuoc phien nam ) OR ((( danh tac van hoc phan nam ) OR ( danh tac van hoc hien nay ))))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( danh ((tac xa) OR (tuc xa)) thai hien nam ) or ((( danh tac dong thuoc phien nam ) or ((( danh tac van hoc phan nam ) or ( danh tac van hoc hien nay ))))))~".
• Adding a wildcard symbol may retrieve word variants: (( danh ((tac xa) OR (tuc xa)) thai hien nam ) or ((( danh tac dong thuoc phien nam ) or ((( danh tac van hoc phan nam ) or ( danh tac van hoc hien nay ))))))*.
