title: [Chen Zutian: the fourth heir to Chen Wailang].
abstract: This manuscript deals with the state of affairs in the Chen-Wailang family, with special emphasis on Soden, the fourth heir to the founder of the Uiro family Chen Wailang. Especially interesting is the library that encompassed much of the medical literature of the time, which may still have a bearing on the modern world.
