Ding Ding is based on Tinker Bell, the protagonist of Doraemon, which is children's favorite cartoon. It looks cute and playful. Ding-ding is pronounced ding and ding, which is the sound made when cups collide or fall to the ground. It sounds sweet and moving. I believe many people like this beautiful sound, and it can also express the sound of a boy's birth and landing. This nickname is pleasant and meaningful, and it is very suitable for a nice boy's nickname.
