Patriotism,which refers to the love of one's country and the willingness to sacrifice for it,is a necessary criterion for us to evaluate one's virtue and conduct.Although Chinese people's patriotism has different contents and features in different historical periods,it's always associated with the love for the country,hometown,and people. Patriotism is a great cohesive force.When the country is invaded or split,people can always defend national unity and unification from the overall interests of the state and thejusticial cause of the Chinese nation under the influence of patriotism. Meanwhile,patriotism is a strong and inspiring mental power that encourages people to render remarkable services and establish a distinguished career for the people and the country.
