The Double-Second Festival (or the Spring Dragon Festival) is traditionally named the Dragon Head Festival, which is also called “ the Day of Legendary Birth of Flowers” , “ the Spring Outing Day” , or “ the Vegetables-Picking Day” . It came into existence in the Tang Dynasty (618AD --- 907 AD).
The poet, Bai Juyi wrote a poem entitled The Second Day of the Second Lunar Month:” The first rain stops, sprout grass and vegetables. In light clothes are young lads, and in lines as they cross the streets.”
On this special day, people send gifts to each other, pick vegetable, welcome wealth and go on a spring outing, etc. After the Ming Dynasty (1368 AD --- 1644 AD), the custom of spreading ashes to attract a dragon was called “ dragon lifting its head” .
