I have a tortoise shell with six stripes, and I want to lend the account of Jianwangsan to a horse dealer. What security protection should I do for the number? What should I pay attention to?

Horse dealer. He needs you to open it, any lock.

You can give it if you are not in a hurry. If you're not worried, don't.

Are you sure he's helping you catch a horse?

Instead of collecting all turtles, just so that no one can compete with him. In any case, he can't just charge you a number. Obviously, it is open to everyone.

Moreover, his own number and money are his own.
