The iPhone cannot recognize the Chinese SSID.
(1) The default character encoding method of SecureCRT itself is GB2312. Log in to AC through CRT, and configure the Chinese SSID on AC to be the encoding of GB2312, but Apple terminal only supports UTF-8 encoding for Chinese, so you need to change the encoding on AC the way.
(2) Use CRT version 7.0 or higher, change the encoding format to UTF-8, and reconfigure the Chinese SSID.
