How to socialize in Bern ?

Hi Internations community,

I have been in Bern for 6 months already but I am feeling like I do not know anybody in the city. I meet only few people and they all got the same feeling. In my last experience, I was living close to Amsterdam and it was much easier to meet new people.
Do you have any tips or plan for me to socialize in the city and to have new connexion ?
I am a french man, 28 years old, and I really looking forward to meet new people :)

Hope to see you soon.
