Poniższy okręt to zaproponowany Chinom w 1916 r. przez koncern Armstronga pancernik obrony wybrzeża. Nie jest niestety znana bliższa historia jego powstania. Wiadomo jedynie że miał być dość duży i raczej powolny, oraz uzbrojony w 4 działa 381 mm i 8 dział 120 mm. Wykazuje pewną wizualną zbieżność z projektem dla Rosji: https://alternathistory.com/bronenosets-nanosit-otvetnyj-udar/ który zresztą był już przeze mnie „przerabiany”, choć dla innego nabywcy (post z 22 listopada 2019 r.). Możliwe, że okręty będące wariacjami tego samego projektu były oferowane różnym państwom, w tym niniejszy wariant dwuwieżowy – Chinom.
