How to ask for speedy-delete of an empty category

[edit]

When you want to ask for speedy-delete of an empty category, best practice is to mark it with {{SD|C2}} if it would be OK to re-create it in the future, given that appropriate content becomes available or {{SD|C1}} if it is an inappropriate category name that should not be reused. In particular, this is better practice than just blanking the category page, as you did at Category:Chenyang Xun. ("C1" and "C2" come from Commons:Criteria for speedy deletion).
