From the Sui on, hanging lanterns on Lantern Festival became a tradition. By Tang Dynasty, lantern fairs on Lantern Festival became a regular practice. This time saw an increase in the scale of the festival as well as the number of days from one day on the Lantern Festival to three days between fourteenth and sixteenth of the first month of the Lunar Calendar. Curfew restrictions were relaxed on these days. The festivals were very fancy, and many professional lantern artisans set up shops on the banks of Qinhuai River.
