In modern China, domestic troubles and foreign invasion were the first national disaster. Only in this way, people with lofty ideals have followed suit, and patriotism has never been higher. Liang Qichao is not only a famous patriot in modern times, but also the most representative figure in the process of China's traditional patriotism from loyalty to the monarch to modern patriotism after the Sino-Japanese War of 1894-1895. Liang Qichao was the first person to systematically expound the theory of patriotism in modern times, because he unveiled the banner of patriotism in the modern sense for the first time. His keen thinking, which is a combination of thinkers and politicians, determines that his patriotism theory is not an abstract sermon, but an ideological guidance that is consistent with his political theory and has practical significance, which has had a wide influence in different historical stages of modern times. Especially after the Republic of China, Liang Qichao's patriotism theory was linked with his own "national consciousness" and sent a message "New Youth", which made his patriotism have a broader vision and richer connotation and promoted to a new realm.
