Teach you to pick a good toilet
An ordinary toilet is about 50 kilograms, while a high-class toilet can meet the requirements of full porcelain due to the high firing temperature, and it weighs about 100 kilograms. So you can weigh the weight of the water tank cover with your hands and perform a simple test~
When striking, if the sound is not clear enough, there may be internal cracking or not being cooked. The high-temperature-fired toilet has a low water absorption rate, will not get dirty and produce peculiar smell~ but the low-grade toilet is just the opposite, not only is it difficult to clean and has peculiar smell, but also cracks and leaks over time!
