it doesn't matter. someone from the industrial and commercial bureau will tell you when you register. If it is too heavy, you won't be allowed to register. Just like Dangdang 123 children's book shopping network originally wanted to use the name Dangdang, because a company has started to use it, it added 123, but this name is also quite pleasant and easy to remember ~ Dangdang 123 network is a special website for children, mainly dealing with books, videos, books for parents and teachers of children aged ~7, and its sales volume is very good, so I suggest that your little red riding hood can be changed appropriately.
