"Rijin Chang 'an" comes from Shi Shuo Xin Yu Su Yu Hui. When Jin Mingdi was a few years old, he often sat on Yuan Di's lap. Once, when someone came from Chang 'an, Yuan Di asked about Charlotte, and he couldn't help but burst into tears. When Ming Di saw this situation, he asked why, and Yuan Di told him about Du Dong. Yuan Di asked Ming Di, "Which do you think is farther, Chang 'an or the sun? "

Ming Di replied, "The sun is far away, because I have never heard of anyone coming from the sun." The next day, at the banquet, Yuan Di asked the same question again, but this time Ming Di replied, "Chang 'an is near." Yuan Di asked in amazement, "Why is the answer different from yesterday's? Ming Di replied, "Because I can see the sun when I look up, but I can't see Chang 'an."

This allusion is often used to describe longing for the imperial city without coming, implying that fame and fortune are not achieved and hopes and ideals cannot be realized.

Enjoy the background near Chang 'an and far away.

When the Eight Kings Rebellion ended, northern nomads took the opportunity to invade the Central Plains, and Emperor Wu of Jin surrendered to Liu Cong from Chang 'an, and the Eastern Jin Dynasty perished, which was known as "five wild flowers" in history. Began the great division period of nearly 200 years. At this time, the northerners of China moved south because of the brutal rule of the Hu people, which was called "crossing the crown to the south" in history.

At this time, northerners often miss their homeland. Although Si Mashao and Ming Di are very young, they can also feel the pain of being defeated by others. Therefore, Chang 'an is used to refer to their homeland, expressing the national grief and grief like people after 900 years. Chang 'an can also mean "long-term stability". There was chaos in the north at that time. Due to the brutal rule of nomadic people in the north, various places rebelled one after another.

However, the south is not peaceful. The contradiction between the original aristocratic families in the southeast basement bucket area and the overseas Chinese in the north, and the political contradiction between Yuan Di and the Wangs led to the undercurrent in the south. It can be seen that the "Wang Dun Rebellion" that broke out soon threw the south into chaos. At this time, Ming Di may have felt the oppressive feeling. At this time, "long-term stability" is undoubtedly an idiotic dream, so he said that "the day is near Chang' an, far away."
