শীতকালে ঘর গরম রাখার দারুন একটি কৌশল | #ghaffarbhai

In China, many traditional homes stay warm all winter thanks to an ingenious design! When building their houses, people install a special stove beneath the floor called a kang. When a fire is lit, the heat and smoke don’t go straight outside — instead, they travel through a network of underground channels. This system evenly warms the floor, keeping the home cozy and smoke-free throughout the cold season. content Declaration: This content is for news and education purpose.
