江南五月,春光明媚。碧绿的田野,湛兰的天空,一片欣欣向荣的景象。几天来,苏北小城建湖县沉浸在节日的欢乐气氛中。长街两旁竖起了林立的标语牌,高悬的彩色气球在空中摇曳,巨大的电子显示屏上打出醒目的字幕…… Jiangnan in May, sunny spring. The green fields and the blue sky of Xilan are a thriving scene. In the past few days, the small northern city of Jianhu County was immersed in the festive atmosphere. There are placards erected on both sides of the long street. Colorful balloons hung in the air. Subtle captions on huge electronic screens.
