Averse to Magnetitum (Cishi) and wine. In grasslands, exuvies of Hui (viper) and Fu (pit viper) are rarely seen; those that are longer mostly belong to Elaphe carinata (Chi Lianshe) or Peltopelma flavogulare (Huangheshe), whose skins are unrecognizable. What is often obtained now is of this kind, and must be complete. Those from rocks are better; when burned, they treat various severe sores.
