tuan trong » thuan trong, quan trong, tran trong
hoc thieu » toc thieu, hoc hien
ho chieu » theo chieu, doi chieu, mot chieu
cong dan » cong san, cong tan, huong dan
chan cau » phan cau, chinh cau, nhanh cau
can cau » van cau, ban cau, ca cau

• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) tinh - thanh trung tuan trong cong dan ((chan cau) or (can cau))*.
