Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thien » hoc hien, hoc thiet, hoc tien
hoc thieu » toc thieu, hoc hien
hanh mang » nhanh mang, hanh trang, nhanh lang
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
mang va » mang vua, hang va, bang va

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: ((hoc thien) OR (hoc thieu)) hach - hanh mang va nhung cong dan ((toan cau) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc thieu)) hach - hanh mang va nhung cong dan ((toan cau) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc thieu)) hach - hanh mang va nhung cong dan ((toan cau) OR (toan ban))*.
