Why is there a water tank in the patio?

The reasons for placing water tanks in the patio are as follows:

1. To store rainwater and avoid excessive water accumulation in the courtyard.

2. In places where water is scarce, water tanks can play a role in relieving water stress. For example, there are huge copper jars on both sides of the Forbidden City, which can come in handy in case of accidents.

3. The water tank also has a certain feng shui effect and the function of attracting wealth. The ancients believed that water can attract wealth, so placing a water tank at home can create the most favorable Feng Shui.

4. In the south, water tanks also have a beautifying effect, such as planting water lilies or raising goldfish in the yard.

In short, the patio water tank reflects the wisdom of the ancients to follow the trend, make full use of rainwater resources, and also reflects their respect and compliance with nature.
