It was not until the recent "sauna sky" struck, and the groundwater level of the Tu Tunquan stopped and declined, and the water level dropped by 3 cm for three consecutive days.

However, the decline of the underground water level of the Tunno Spring did not last long. After the beginning of the autumn, Jinan ushered in the continuous rainfall for many consecutive days to help the Tu Tuquan stopped falling and rebounding.
