The paper deciphers the Chinese literature to English speaking scholars and bridges the gap between China and the western countries on the topics of therapeutic landscapes and healing gardens. Three parts of contents are included in the paper. Firstly, four schools of theories explaining how and why nature can heal, are introduced based on the studies in western countries with the examination of terminology used. In the second part, 71 publications in Chinese are systematically reviewed, with 19 significant studies analyzed in details, including focus areas, the research method, and major findings. In the final part, Chinese studies are evaluated in relation to the theories in western countries.

Chroniosuchians are basal tetrapods owing to Anthracosauromorpha and the oldest species of chroniosuchians have been recorded in the Late Permian of Russia so far. In this study, we present evidence for their existence in the Middle Permian of China, based on well preserved diagnostic vertebrae with associated osteoderms from the Dashankou fanua in northwestern China. The finds clearly show interosteoderm articulation pattern between the adjacent scutes in bystrowianids. The features observed in Yumenerpeton yangi may warrant the close proximity or phyletic succession of the chroniosuchid and bystrowianid types of the osteoderm design.
