Tongjian Lake in Shuangpu Township of West Lake District welcomed its golden autumn, with "rainbow trees" seeing everywhere. They are metasequoia trees around the lake. Taking on gradient colors from fiery red to golden yellow and then emerald green, the trees present a riot of colors and get clear reflections in the water, creating a captivating autumn view. 

Under the influence of temperature, the metasequoia trees would soon turn dark brown. The view of “rainbow trees” would not stay long. It is a golden time to admire the view by boat before the end of November.
