From Coffee blog:
This mother, who lives in Chongming county of Kunming city, lost her son, Zhao Zhanying, 20 years ago during the Sino-Vietnamese War. Twenty years later, she saw her son’s tomb for the first time at Yunnan Martyr’s cemetery with the help of her son’s comrade in the army. She didn’t have the trip fare. After her only son died, her husband also passed away soon after from grief. The local government gives her only 28 yuan ($4) each month for living expenses. People were surprised to see how poor she was when they saw her home. The 28 yuan is her “compensation” for losing her son.
