Because of the need for drawing the "Many Turtles" picture book last semester, the children specially studied the appearance of sea turtles. In addition, they happened to learn symmetrical figures in the field of mathematics, and discovered that the carapace of the green sea turtle is line symmetrical. Extended to other marine life, crabs, octopuses, fish...etc., so in the end, we combined the elements of the ocean and Wang'an Elementary School to design a logo that is unique to Wang'an Elementary School.
