Shanghai's Peace Hotel 1985: Chinese forbidden

The Peace Hotel's famous coffee shop--staging a Jazz Band whose members were already playing in the 1940s--was opened only for foreigners and the oversea Chinese compatriots in the mid 1980s.

The Huangpu Park (黄浦公园), located not too far from the Peace Hotel used to have a sign that carried the message 'dogs and Chinese not allowed'.

Any thoughts on the two signs?
