Did you recommend a children's science fiction novel?

It was published a long time ago. I don't remember the author. It's from China. There seems to be only two words in the author's name. The title should be called Coco's Adventures on Earth. At the end of the book, it seems to say that there's a sequel, which is an adventure in the universe. Unfortunately, the book was lost later and I didn't finish it. It probably says that a boy on Earth named Coco met a boy from the future one day. I think I gave myself a name called Jing Jing (like a girl). I don't know what kind of medicine the doctor made Coco drink, but she became indestructible. Even his family was immortal. Later, the earthlings fought over him like snatching the Tang monk. The building he lived in was crushed. So he was brought to the future by Jingjing to live. Then he went to some school to learn some skills and then went on adventures in fairy tales and sci-fi worlds. Anyway, when he was young, he thought it was very good. Unfortunately, he couldn't find it on the Internet. Now he wants to look for it again. I hope that any brothers and sisters who know can give me some clues. I'm very grateful!!!!! Faint, no one knows????? Sigh, really can't find it? In the story, there are also scenes of killing the evil sharks in the sea, going to the North Pole to find the Fire Dragon King, the hair on the head is a fire-breathing snake, the two little masters also know Sun Wukong, the White Dragon Horse, etc., and they know how to change seventy-two times and so on. I can think of other things to add!!!
