What's the difference between traditional poetry and new poetry?

Although the traditional form of poetry still has some vitality in expressing the poet's life feelings, it is obviously not suitable for the ever-changing social life. Then came the revolutionary "New Poetry School" represented by Huang Zunxian. His poems reflect War of Resistance against Japanese Aggression and many important historical events since then. He advocates that "I can't make a book by hand" (miscellaneous feelings). His works have introduced many new terms, reflected new cultural knowledge, described the customs outside China, and greatly changed the face of China's classical poetry, which is refreshing.
