Hot spicy chicken and eggplant, Shark's fin soup

Today's cooking is Chinese meal. One dish is chicken and eggplant with many chili and Chinese black vinegar.
Another dish is soup. My brother is working at China, and he gave me shark's fin when he came my home. Shark's fin is premium food. I soaked and washed fin, then boil them for some minutes. After it went soft, I made oil flavoured with Chinese sake, garlic, welsh onion, and ginger in fry pan. Pour hot water and boil fin in it again. Boil water in another pot, and put chicken powder, Shiitake mushroom, pepper, salt, potato starch. Take fin from fry pan and put it into pot. Finally, put raw egg and stir. Hew.
