The first one is the stone trough, which is very popular to dig a trough to make a rice bowl for livestock. Now it is hard to find a trace. Because people's family conditions were not very good in the past, many rural people supported themselves by raising livestock and farming and selling money. Because pigs, cows and other animals are very strong and often accidentally knock over stone troughs, stone troughs became popular later. However, with the development of the times, stone troughs have been replaced by steel and plastic products, and farmers are raising pigs and cattle less and less.

The second is the stone mill, which used to be very popular in the countryside, but now it is an antique. Because there were not so many machines before, whether farmers wanted to eat rice or white flour, they all ground it in a stone mill, and the sound of stones rubbing against grains was particularly fun. With the increasing popularity of mechanization, the stone mill has withdrawn from farmers' lives and gradually become an antique.

The third is the water tank, which used to be a necessary daily necessities for every household in rural areas. Now many water tanks have disappeared. Because in the past, there was no running water in the countryside, and all of them drank well water, so every household would use water tanks to hold water. Nowadays, with the development of tap water in rural areas, water tanks are basically useless, and many water tanks are damaged by their owners because they are too big to put down. So now water tanks are also rare objects in rural areas.

The fourth kind is sickle, which has been popular in rural areas for thousands of years. Because of the popularization of mechanization, it gradually withdrew from the historical stage and became an antique object. In the past, in the countryside, every household would take out a sickle and grind it, and then harvest the crops. Now, with the increasing number of large combine harvesters, farmers no longer need to harvest crops with sickles, so sickles have become a rare antique.
