The Cole Flowers Tourism Festival is held every year in Nanjing’s Gaochun district from March to May. During this time, Gaochun is full of golden color. You can ascend a mountain to enjoy a panoramic view of the 10,000-acre golden cole flower sea, which is in harmony with the tea garden, bamboo forest and wheat field. You can take photos in the cole flower field, pick tea from the tea garden, dig wild vegetables in the field or ride a bike to see around.
