Through Cedric's viewfinder

Every weekend, parents of shanghainese youth gather in People’s Park in order to find their heir a wife or husband :
You can see ads like this pinned on trees, or on the wall :

“young man, 26′s, 1.85m, bank accountant, looking for youg woman, max 26 years old, > 1.6m with goodjob”
or vice-versa.
If interested, then you can ask the parents standing nearby for a picture of their child and discuss important things with them, before organizing a blind-date!
