1. Off from your subject here. 不仅不懂 “海带御潜艇' and 不仅不装懂. but like to eat 海带 especial those produced around seashore of 青岛.
2. Was born in 青岛. Love 青岛, 青岛栈桥 and all of the seaport very much. Had spent my pre-teen at there. It had changed a lot when i accompanied my father to visit it some time ago. Most beautiful city to me than any others i have seen. Wondering how long 翰山 comrade stationed there? You know about it almost as i do.
3. General Zhang is probably kidding or mouth-slipping, may be. What his “海带御潜艇' means '海带御 frogmen' (coming from Taiwan, that was disbanded long time ago) instead. Ha-ha!
