[[P]]: Cascading protected.
Content: {{:汉}}

[[汉]]: Not exists.

[[漢]]:
Content: 123

Currently, [[P]] displays 123 and [[漢]] is protected. A user (not sysop) can create [[汉]], with the content 4321 for example, then purge cache (all pages above, I'm not sure whether this is necessary). Now, [[P]] displays 4321, besides, [[漢]] becomes unprotected and [[汉]] becomes protected.
