(Continued from the previous post.)
At least two of the works on the graffiti wall included people wearing respiratory masks. Whether related to corona or to air pollution, I'm not sure. Perhaps both?
Not sure what this one is supposed to represent, but s/he does not look happy to me.
A lot of the the graffiti was of the "tag" kind (I think it's called??) - and did not really "speak" to me at all. But I suppose there may still be a lot of symbolism hidden there even if I'm unable to interpret it.
