Origin Story
唐朝时期，长安城繁华热闹，大街上人来人往，川流不息。各式各样的商品琳琅满目，比比皆然。有来自西域的奇珍异宝，有南方产的丝绸锦缎，也有北方特产的皮毛药材。店铺酒肆更是遍布大街小巷，热闹非凡。每逢佳节，更是人山人海，热闹非凡。就连城外的小村庄，也因长安的繁荣而变得富足起来。百姓安居乐业，国泰民安，这盛世景象，真可谓比比皆然。
During the Tang Dynasty, the city of Chang'an was bustling and lively. The streets were filled with people, a constant coming and going. Various kinds of goods were plentiful. There were rare treasures from the West, silks and brocades from the South, and furs and medicinal herbs from the North. Shops and taverns were widespread and lively in the streets and alleys. During festivals, it was especially crowded. Even the small villages outside the city prospered due to the prosperity of Chang'an. The people lived in peace and prosperity; this flourishing scene was ubiquitous.
