nhung cong » dung cong, thong cong, hang cong
thi chieu » thi chien, thi hieu, theo chieu

ho chieu » theo chieu, doi chieu, mot chieu
trong va » trong van, trong ca, trong cac
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan

• Adding a wildcard symbol may retrieve word variants: ((((ho chieu) or (hoc thieu))) or (thi chieu)) xanh - hinh trong va nhung cong dan toan tap*.
