phuong dan » phuong danh, phuong doan, huong dan
chinh cau » chinh chau, chinh can, chinh tai
chu tinh » chau tinh, chua tinh, chu tich
chinh su » hinh su, chinh phu, chinh ta
chinh ca » chinh ta, chinh va, chinh tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chu tinh) or (cuu tinh)) - hanh chinh su dung phuong dan ((chinh cau) OR (chinh ca))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chu tinh) OR (cuu tinh)) - hanh chinh su dung phuong dan ((chinh cau) OR (chinh ca)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chu tinh) or (cuu tinh)) - hanh chinh su dung phuong dan ((chinh cau) OR (chinh ca))".
• Adding a wildcard symbol may retrieve word variants: ho ((chu tinh) or (cuu tinh)) - hanh chinh su dung phuong dan ((chinh cau) OR (chinh ca))*.
