Is there a place in the Forbidden City to store luggage?

Yes, I choose the “Xiucai Speaks”讲解服务, next to the gathering point, at the location of the audience service center.
Yes, there is one next to the Meridian Gate, very convenient. If you need an interpreter, I recommend Xiucai. He’s very reliable; I’ve followed him.
Should be there, but I don’t know where.
The entrance to the Forbidden City is the Meridian Gate, which is an entrance-only. There is a place to deposit bags at the Meridian Gate entrance. The exits of the Forbidden City are at the Shunwu Gate and the Donghua Gate, both of which are exit-only. You can leave after two hours of visiting, pick up your bags outside the Shunwu Gate, which is very convenient.
