张青

Zhang Qing is an author about whom limited public information is available; existing records do not specify nationality, dates of birth and death, or professional background. Four works by this author are held in the collection, spanning medicine, finance and economics, and management: professional material on the management of sterile supply centers and related technical guidelines; a finance-oriented study of Hefei's development path through the lens of the "innovation quadruple helix"; an introductory project management book for junior project managers; and a title on hospice care that touches on medical humanities. Judging from these choices, Zhang Qing's writing combines practical operations with knowledge popularization, focusing on organizing professional processes, methods, and experience into clear, readable guides. The prose is plain and emphasizes applicability. The wide range of subjects reflects sustained attention to healthcare management, urban innovation, and project practice, making the works suitable as references for practitioners and newcomers in these fields.
