I buy things for my children in Pinduoduo. Can he understand?

I can't. On the Pinduoduo, the recipient only wrote someone else's name and telephone address, and Pinduoduo officials could not tell the recipient. Others will not know when they buy things for others. If you want to remind your child to receive the goods, you can check the logistics, remind and tell your child when you deliver the goods, otherwise the child will refuse because he doesn't know who bought it.
