Today, Beijing and Tianjin will start experiencing flying flowers. The flying flower period starts earlier, so beware of the "flammability" comparable to gasoline.

Due to the rapid increase in temperature since late March, the development process of plants has accelerated. It is expected that the overall flying time of poplar cotton in central Hebei and the Beijing-Tianjin region this year will be 1 to 2 days earlier than last year. Over the next 10 days, sunny and hot weather will dominate most parts of the Beijing-Tianjin-Hebei region, with temperatures rising rapidly. Poplar cotton will mainly fly in the 10 days after the Qingming Festival. Beijing and Tianjin will enter the peak flying period of poplar cotton after April 15th.
