Perhaps you should try some spelling variations:
thien thanh » tien thanh, thi thanh, hien hanh
phung cong » nhung cong, phong cong, nhung chong
hoc thien » hoc hien, hoc thieu, hoc thiet
hanh luat » hang luan, hanh lam, dan luat
van phung » van phong, van hung, van chuong
van than » van thanh, van thang, van tuan
dan chan » dan gian, dan ca, van chat

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc thien thanh - ((hanh luat) OR (nganh luat)) van phung cong ((van than) or (dan chan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thien thanh - ((hanh luat) OR (nganh luat)) van phung cong ((van than) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thien thanh - ((hanh luat) OR (nganh luat)) van phung cong ((van than) or (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: hoc thien thanh - ((hanh luat) OR (nganh luat)) van phung cong ((van than) or (dan chan)) cau*.
