Linternas chinas

A little church in the middle of the city, grass beyond the gate and all around it. First I thought they were pieces of plastic, then tomatoes (December? outside?). Still non the wiser... some sort of seed pocket? It's so difficult to find a splash of colour in the midst of winter (even if, officially, it's not winter yet!).
It's really really cold today, freezing fog they say. Glad I don't have to go out, again.
