Cang Kejia put great emphasis on writing only what he is familiar with, which is a major feature of his realism. On the relationship between "the needs of the times" and "being familiar with oneself", he emphasized familiarity with the subject matter. Of course, with the changes of the times, poets should be familiar with the new and unfamiliar life in the past, which is complete realism. In his preface "A War in the Middle" for Song of the Earth 1946 edition, he said: "When can I stop worrying, grieving and angry about their tragic fate and sing such ugly songs? When, let me sing a happy and liberated song for them-China farmers, in truth, just like they sing a sad song? " He was familiar with farmers in old China, so he wrote about farmers in old China. But he also longs for new people and a new world.
Cang Kejia loves the Party, the people and socialism, and earnestly studies Marxism–Leninism, Mao Zedong Thought, Deng Xiaoping Theory and Theory of Three Represents. In his creative career of more than 70 years, no matter during the revolutionary war years or during the period of socialist revolution, construction and reform and opening up, he cared about the future of the country, the destiny of the nation and the development of literature with great enthusiasm, enthusiastically eulogized the cause of revolution, construction, reform and opening up and socialist modernization led by the Party, and actively advocated writers to go deep into life with short poems, old poems, essays, critical letters and novels. He adheres to the direction of "choose one from two" and the policy of "letting a hundred flowers blossom", unites and cares for middle-aged and old-aged poets and enthusiastically cultivates young poets. He witnessed the whole history of China's new poetry from birth to development, and made outstanding and indelible contributions to the development of China's new poetry.
Cang Kejia's life is a life of unremitting pursuit of light, a life of consciously expressing the times and serving the people wholeheartedly, and a life of diligent writing, painstaking efforts and constant climbing of artistic peaks. He is keen in thinking, clear in love and hate, kind and upright, optimistic and open-minded, decent in style, simple in style, approachable, open-minded and cheerful, frugal in life and strict with himself. He devoted his whole life's energy and painstaking efforts to the literary cause of the party and the people selflessly.
