Wuhan / 武汉 | final letter / 遗书
要求平等合理赔偿 (on the wall it's written with 尝, but I think it should actually be 偿)
A rough translation:
[I] will perish with the shop
Demand equal and rational compensation
After [my] death, the government [has to] provide for [my] elderly mother, wife and child.
It's a silent protest that has been going on for over a month now, with all the shops on this section of the street displaying banners and posters with similar texts, demanding fair compensation. This is the most dramatic one. Seems that the demolition will start in a couple of days, the last shops there being open for the last day tomorrow.
