Can I bring my own swimming ring to Bali? And the hotel swimming pool must wear a swimming cap? Tell your friends who have been there.

But it has its own swimming ring. But you have to let go. You don't have to wear a swimming cap to swim in the swimming pool. But there's a reason to wear a swimming cap. The first reason is that the water in the swimming pool needs to be filtered and disinfected every day, and a hat is needed to protect the hair. The second reason is that the swimming pool is a public place, and it is necessary to wear a hat for the health of others. The third reason is that swimming pools nowadays are generally filtered circularly. If the hair falls into the swimming pool and gets stuck in the circulation system, it will seriously affect the use and life of the machine.
