Perhaps you should try some spelling variations:
luan thien » luan thiet, luan nghien, luong thien
thien danh » thien anh, thien dang, thien thanh
nhung cong » dung cong, thong cong, hang cong
trinh vai » trinh tai, trinh vat, trinh va
trinh van » trinh han, trinh quan, trinh toan
cong dan » cong san, cong tan, huong dan
toan cao » toan tap
toan ban » van ban

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: luan thien danh - hanh ((trinh vai) OR (trinh van)) nhung cong dan ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "luan thien danh - hanh ((trinh vai) OR (trinh van)) nhung cong dan ((toan cao) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: luan thien danh - hanh ((trinh vai) OR (trinh van)) nhung cong dan ((toan cao) or (toan ban))*.
