We cannot risk kerosene or electric lamps. We must make our buildings look as if they are uninhabited.All day yesterday we could hear explosions from the direction of the Rain Flower Terrace. I told Shujin it must be our military blowing trenches outside the city wall, or destroying the bridges over the canal, but in the streets I heard people whispering, ‘It’s the Japanese. The Japanese.’ Then, earlier this afternoon, after a long period of silence, there came an almighty explosion, shaking the city, making Shujin and me stop what we were doing and turn to each other with deadly pale faces.‘The gate,’ shouted a boy from the street. ‘Zhonghua gate! The Japanese!’I went to the window and watched him as he stood, his arms stretched wide, expecting shutters to fly open, voices to answer his, as would ordinarily be the way. Usually our lives are lived in the streets, but on this occasion all that could be heard up and down the neighbourhood was the furtive barricading of doors and shutters.
