We have built 5 solar photovoltaic power stations, with a power generation capacity of 5.91 million kWh in 2021. In the future, we plan to build 3 additional solar PV power plants in 2022, with an estimated electricity generation of 13 million kWh; by 2025, we expect to build more than 10 solar PV power plants. In addition, we are also acquiring green power through purchasing green power certificates. In 2021, the cumulative green power usage totaled 15.91 million kWh.
