5 months old baby looking for new friends ;-)

Hello,
I am a new Mum in Beijing. My little Julia is 5 months and we arrived 3 weeks ago. We are French. My husband and I, we are both working in Beijing. Hence It is very difficult for us to meet people and to find parents who have children of the same age of Julia. We would be glad to meet new people and to go to events but we dont know when and where they are organized. Please share with us any event that you might know by replying to this post and we would be glad to come...
