Usually, the extended period won’t exceed the duration of stay of your current M type. Maybe you can do the extension twice, but I cannot guarantee the result. You can try to apply for an extension 7 days earlier before your M type expires. First, prepare your passport and valid registration form of temporary residence, the application form, passport-style photo, and others, and then submit the application to the exit and entry administration of the local PSB to apply for the extension.
