清朝(チャイナ)の領土は広大に描きながら、海南島すらその領土として描いてない。
台湾島も清朝の資料を基に描いたと思われ、当時の台湾府の領域である西岸部から山脈部までの形である。
However the land of Qing was depicted as its vast extent, the Hainan Islad was not coloured as its territory and the shape of Taiwan Island was the half of its figure.
No ruling trace of Qing Dynasty in the South China Sea and the East China Sea.
当時の清朝が自己都合により、台湾島を化外の地とし、時に「中華」外としていたことを裏付けている史料と言えよう。
