Tung trees were mainly planted at places where Hakka people live and are a significant symbol of Taiwan Hakka culture. Tung Trees are deciduous trees that can grow up to about 20 meters tall, can be commonly found in southern China, Burma, and mostly northwestern Taiwan. Large numbers of Tung Trees were planted during the Japanese colonization period in the hills of Miaoli as the location has the ideal condition for its growth. In the past, most of the Hakka people made living by extracting oil from Tung Tree seeds, flowers as food ingredients, and wood as raw materials. Today, Tung trees are no longer the major crop of Hakka as there are cheaper alternatives, but Hakka people still cherish for the good things that Tung trees have given them in the past.

There are two species of Tung Trees in Taiwan include aluerites fordii hemsj that blooms around April to July and aleurites Montana that blooms a bit earlier, from March to May. Tung Blossoms are favored for their appearance of pristine white petals and red filaments with yellow anthers. When it comes to the Tung blossom festival, these beautiful Tung blossoms cover the country roads and hills in large numbers and size, providing mesmerizing sceneries just like a layer of snow.
