On November 20, leaves of the sycamore trees along the Beishan Street were already yellowish, whereas Salix leaves and ryegrass sprouts on Baidi Causeway were as green as jade. It presented a view in which a golden street and jade-like causeway circled the West Lake. Although it had approached the Lesser Snow solar term, Hangzhou had not officially welcomed its winter. It has been very clear over recent days and the highest temperature stays above 20℃, thus being an ideal time for admiring the scenery of Hangzhou.
