I want to buy a scarf to free my hands, but I am puzzled about what kind of good it is. Please ask my sister for advice!

Let me answer that. Write about my use of scarf straps for the landlord's reference only. I used a homemade double-ring scarf for Bauer, which is both labor-saving and a sleeping artifact. But it's a little hot on a hot day, so is a homemade double-ring scarf. I have a self-made X-strap with zipper front and a baby strap in six. It's useless to be afraid that the baby will be uncomfortable sitting inside. I gave it to my cousin, who wanted to buy a strap to hold her baby daughter. A few days ago, I saw relatives and neighbors using a traditional back quilt (strap) from Taobao, Guangxi. It seemed good in summer, and I ordered one today.
