2018 is the 200th anniversary of the birth of Marx. Different countries around the world have commemorated this great man in different forms. People have retraced Marx’s life，reassessed and paid tribute to Marx，and enthusiastically discussed the historical significance and contemporary value of Marxism. The outbreak of the financial crisis has caused the West to “rediscover” Marxism. The awakening of young people has also had a significant impact on the political ecology of Western countries. For socialist countries and the Communist Party，Marxism has been given new vitality in socialist practice. Although Marxism still faces some doubts and challenges，it will continue to lead the 21st century world socialism to revival.
