My family and Zhao Zhenguo have been neighbors for three generations. When the homesteads were divided, there was no way out between the two families, so my grandfather took the initiative to discuss it with Zhao Zhenguo's grandfather. Each family gave up 2 meters of homestead land and left a 4-meter-wide outlet. Zhao Zhenguo's grandfather promised, but when his family finished building the house, the outlet was only 3 meters wide, and his family only gave up 1 meter.
