Brand, the first book of poetry published by 1933, is his most influential work. This collection of poems sincerely and simply shows the decline of rural areas in China, the sufferings of farmers, perseverance and national worries.
During this period, Cang Kejia's poems were short, but they were quite general. In addition to consciously learning the structural methods of classical poetry, he formed a dignified, concentrated and refined style, and deliberately pursued novelty, originality and visualization of words, but at the same time he was plain, clear and colloquial. After the founding of People's Republic of China (PRC), Cang Kejia wrote many political lyric poems, which are his representative works. Some people wrote this poem to commemorate the third anniversary of Lu Xun's death/kloc-0. Its uniqueness lies in its philosophical theme: man lives for the better of most people. In fact, this theme has gone beyond the scope of praising Lu Xun's spirit and introduced readers into deeper thinking about life. Simple language, strong contrast and vivid image are the artistic characteristics of this poem. In addition to continuing to write short and meaningful poems, Cang Kejia also wrote a biographical poem "Li Dazhao". This long poem shows the great and ordinary personality of a revolutionary pioneer from many angles such as fighting and family.
