A nice postcard from Macau showing cannon placements in an old fort (?). The sender is from Liwan 荔湾区 , an urban district in the city and province of Guangzhou. It is an area of 63 square kilometres and has 1 113 000 residents. On the back of the card the sender used postage stamps with Cao Yu 雷雨 (1910-1996), a Chinese dramatist. The sender says his favourite Cao Yu play is Thunderstorm. Thunderstorm was written in 1933. It tells a story of the disastrous effects of rigid traditionalism and hypocrisy on the wealthy, modern, somewhat westernized Zhou family. It centres on the Zhou family's psychological and physical destruction as a result of incest and oppression, caused by morally depraved and corrupt patriarch, Zhou Puyuan, a wealthy businessman.
