Italian - Can I get "3" month (single or muliple does not matter) tourist visa

Do you mean you plan to stay in Chna for 3 months. The duration of a China tourist visa is usually 30 days, and only for the purpose of visiting families, can the applicants be granted a longer duration. If you will only go to China for sightseeing, I think it's impossible for you to be given such a long duration.
