A key principle of the torch relay is to try to ensure the Paralympics and Olympics are "equally splendid". "We need to show our inclusiveness and our care and respect for people with disabilities," Xu said.

About a fifth of the torchbearers will include people with disabilities. To ensure the safety of the disabled torchbearers, the organizing committee has prepared barrier-free facilities at all relay points.

Each disabled torchbearer will be assigned an assistant. There will also be sign-language interpreters, guides for blind people and backup wheelchairs during the torch relay.
