Literary children’s science fiction calls for works that are both literary and scientific. Zhang Zhilu，with his delicate emotions，intricate plots, and elements of science fiction，has promoted the development of literary children’s science fiction and brought many classic science fiction novels and films to young people. Since the 21st century，Ma Chuansi’s works have been constructed and developed along the path of literary children’s science fiction. Ma Chuanyi gallops through the real and imaginary worlds with poetic language，cares for the grand narratives of contemporary times from a delicate child’s perspective，deeply explores the philosophy in the current reality and science fiction world，and strives to create excellent children’s science fiction literature for children that is full of unique life experiences and emotional care. His works have played a bridging role in the division of the 21st century children’s science fiction category and the development of literary children’s science fiction.

In the context of high-quality development, science writing in the new era faces multiple challenges from macro，meso and micro perspectives. Since the 1950s，relevant policies and studies at home and abroad have shown that cooperation is an important way to promote scientific researchers to carry out high-quality science writing. Combined with cases such as China’s Road to Science and Technology：Water Conservancy Volume：Water for Livelihood and China’s 4th National Climate Change Report：Public Edition，the paper explores and summarizes the“three-plus-three”cooperation mode of science writing. This model can effectively drive researchers who have a strong desire to popularize science，but relatively short of time and ability，and help expand the team of science writing and promote the prosperity of science writing.
