1. "Wind and rain" is both real life and a symbol of the fate of the Southern Song Dynasty. The poet associates the crumbling situation of the Southern Song Dynasty from "wind and rain", and naturally connects reality and dreams, integrating the dream of "Iron Horse Glacier" and his life ambition of "defending Luntai", expressing his patriotism. (Just stick to the double meaning of "wind and rain" and answer from writing, thinking, etc.)
2. Full of enthusiasm and unswerving determination to serve the country.
