By 7 o'clock this morning, the water level had dropped to 7.33 meters, 7.8 meters below the guaranteed level.

The most unusual sight along the Xin’an River is the wondrous mist that lingers over Baisha Town due to the river’s temperature, which stays at a steady 14 to 17 degrees Celsius. In the mornings and evenings, the surface of the river is cold, which creates a large temperature difference between the water and the air. This causes the formation of the white mist that distinguishes the landscape. With the discharged flood, the mist has come along with the flood. Many netizens photographed the Qiantang River as "fairyland" this morning!
