Define a factory interface. Q: How will it be realized? A: Declare a factory abstract classFor example, I opened a restaurant that normally can accommodate up to 30 people at the same time. You go straight into the restaurant, find a table and sit down to order, and you can eat immediately.这绝不是青鸾公主的作风。大唐初年乃中国历史上最为兴盛的历史时期，明群贤相，政治清明，尤其是天宝年间的贤相房玄龄更是为后世景仰，然而他却有一个被人诟病的话题：怕老婆！Take steak as an example. I only like medium rent when eating steak, that is, it is 3-4 rare. In the past, depending on the thickness of the steak, the central temperature will reach about 50 degrees when each side is fried for 1-2 minutes. At this time, the inside of the steak will be very attractive red and the taste will not be tender. In addition, when processing some seafood products, the temperature can be fixed in the range of 70-90 degrees, thus prolonging the cooking time, thus better ensuring the taste and preserving nutrition. Finally, since the food materials in the vacuum sealed environment have little contact with air and the juice can be locked in the bag, the produced food materials will be more juicy and will not be oxidized and discolored.怎么就不知廉耻了，人家不是换铃么？没钱买拿东西换也理所应当。
