Closed and restricted both mean not open to everyone, but they point in opposite directions after 'to': closed to names who is excluded, restricted to names who is allowed in, based on formal rules. Closed can also mean a shop is shut, not compared here.

这两个词都表示“不对所有人开放”，但方向相反：closed 后接 to 时，说明的是被排除在外的人；restricted 后接 to 时，说明的是被允许进入的人，且 restricted 更强调基于规则或安全考虑的正式限制。这里不比较 closed 表示“（商店等）关门、停止营业”的意思。
