The courtyard doesn't have central heating, but during the last renovation, heating pipes were installed underground. There was already underground heating in ancient times, so it's not really a surprise. However, heating from the outside would consume too much coal, and at that time, coal was still rationed. But Qin Xi somehow managed to get a batch of coal, almost half a truckload, enough for three meals, so there was no need to worry about coal anymore.
Qin Zhen had returned three days ago, and he had completely changed his style. He wore skinny bell-bottoms with a trench coat and long hair, which angered Qin Xi so much that she dragged him to the barber shop, where his hair was cut into a crew cut, and his bell-bottoms were forcibly changed to light silk cotton pants. His thin trench coat was also replaced with a thick military cotton-padded jacket.
