Obtain Stay/humanitarian Visa want to change to Tourist L

Right now I am on a Stay Visa here in Shanghai. (live here for 9 years had several work and Student visa)

I would like to Change to a Tourist L which I have to leave the Country.

I heard in Hong Kong it is very difficult now to get the L ( I never applied before in HK).

Anybody knows what would be the best Option to apply for a L?

I am a german passport holder
