As you make your way through the crowded stalls of Beijing's food markets nowadays, you may sometimes be confused as to just what you should be looking for. There is a profusion of fresh vegetables laid out for sale, so much celery, so many Dutch beans, tomatoes, even broccoli and parsley. How different things were only a scant 15 years ago. At that time there was no variety in the selection of vegetables. Today, with bread, jam, milk and eggs available for breakfast instead of porridge, deep-fried dough strips and pickles, more and more people can afford the indulgence of eating whatever they want.
It is all the rage for fashionable teenagers to go to a Western restaurant for spaghetti, a hamburger, filed chicken, pizza or a sandwich. Older folks in China have not quite caught on to these trends, as their younger counterparts have, and tend to be more practical, focusing their attention on simple but sensible food. The purpose of eating is not simply to fill one's stomach, they mason, but also to maintain one's mind and body. Products like low-fat foods, vegetables, bean products and "black food" (foods dark in color, believed to be highly nutritious) have all won over many older consumers who would probably blanch at the thought of a McDonald's Happy Meal for lunch.
It is an old Chinese tradition to attach great importance and ceremony to the art of dining. When friends come for dinner, they are often treated to a sumptuous banquet, which results in a lot of wasted food. Young people nowadays pay more attention to quality than quantity, though, and innovative contraptions like chafing dishes are starting to appear on Chinese tables instead of the old "eight courses (usually four meat dishes and four vegetable dishes) and one soup" allowing diners to chat while they eat. Some companies are now beginning to treat guests to buffets instead of the traditional big banquet, which helps in turn to cut costs.
China is well-known for its food, and that is saying a lot. The famous "eight cuisines" of Chinese kitchens have won accolades from customers as far afield as Capetown and Salt Lake City. But preparing Chinese dishes is no easy job, and it takes one or two hours to serve up one dish with the right flavor, color, taste and shape to satisfy demanding Chinese palates. People of the 1990's just don't have the time any more. Affluence brings more fast food and instant meals in a box, especially frozen food, and the introduction of electric steamers, microwave ovens and electric ranges gives many people an excuse to spend fewer and fewer hours in the kitchen preparing a decent meal.
What did Chinese people usually have for breakfast 15 years ago？
