In rough chronological sequence, and in brief, Chang's first view on WWI was to regard it as a god-sent golden message and lesson to impel China to seek out ways and means to become a rich and powerful nation (this may be called "the key to the nation's strength and power); his second view on WWI was to regard it as an opportunity to join the world of nations with equal status and dignity (this may be called "the necessity to declare war on Germany and Austria"); his third view on WWI was to regard it as a crisis of European civilization and as a harbinger to socialist society (this may be called "the advocacy of 'socialism'"); his fourth view on WWI is contained in his book "On National Constitution" informing an attempt to collapse socialism with the chance to revive China's civilization through regeneration of Confucianism (this may be called "the future of socialism and Confucian world).

按时序先后简言之，他对欧战第一个看法是把它当做鞭策中国往富强之路之借鉴（可称之为「富国强兵」之钥）；第二个看法是把它当做中国跻身世界之林的机会（可称之为「对德、奥宣战」之必要）；第三个看法是把它当做欧洲文明危机与社会主义到来之诤言（可称之为「社会主义」之讲求）；第四个看法是在《国宪议》中把社会主义与中国文明复兴之契机连在一起（可称之为「社会主义和儒家世界」之未来）。

Thus, it is very important to carry out the research in understanding theessence of vacuum such as vacuum condensate.
