Later, because merchants and others taboo unlucky words such as "Qing" and "Guang", some people took the word Yangchun in the ancient music title "Yangchun Baixue" and renamed it "Yangchun Noodles". The method of making this noodle is simple. Put hot noodles in a sauce-hemp soup bowl and decorate it with green chopped green onion. When talking about the popular breakfast in Shanghai, many people often associate Yangchun noodles and other cakes, fried dough sticks, rice and soybean milk known as "four donkey kong", and at the same time classify them as common breakfast to show their low grade. Yangchun noodles have two kinds: wide soup and crossing the bridge. The former refers to a bowl with more soup and less noodles, while the latter refers to a bowl with less soup and more noodles. After the opening of Shanghai, many noodle restaurants improved the soup of Yangchun noodles, which was boiled with meat and bones, and also with fresh fish, making the soup rich and delicious. The famous restaurants in Shanghai at that time, such as "Lao Ban Zhai" and "Si Ru Chun", were all good places to eat Yangchun noodles.
