Why is Liu called Ma Biao?

Because Ma is three years older than Liu, he is his brother. Although Ma is three years older than Liu, he is still very young, so Liu is called Mamak.

Liu likes horses very much and is very kind to them. He completely regards him as his own brother. After all, he is the elder brother who has been leading since childhood. Some fans who have just become fans of Liu may not be familiar with him. In fact, both Liu and Song are very dependent on horses, and they always like to praise Mark, and their mouths are sweeter than each other.

Now that they are all grown up, Liu doesn't call him Mark, but directly calls him Kyle. Sometimes he is very naughty and calls horses by their names.
