 games is counted as two MPUs. The Average MPU for a specific period is calculated by averaging the MPU for each month within that period. We believe that MPU is a useful metric to measure the monetization of our games.

(1) Quarterly Average MPU refers to the Average MPU calculated on a quarterly basis, facilitating year-over year comparisons.

The average MPU for Q1 and Q2 of 2025 were 36,349 and 34,517, respectively. This change was mainly influenced by the following factors: firstly, in the second half of the 2024 fiscal year, multiple main products focused on marketing and content updates, driving MPU to reach a temporary peak; At the beginning of 2025, as key products such as “Wei Shu Wu” entered a stable operation stage, the conversion rate of new users and the number of active paying users tend to normalize. Secondly, the Company had made adjustments to its resource allocation, focusing more on long-term operations and cost efficiency optimization. The reduction in early promotion investment has also had a certain impact on short-term MPU. Nevertheless, the overall MPU remained in a healthy range in the first half of 2025, laying a solid foundation for the subsequent launch of new products and adjustment of operational pace.

Average Revenue per Paying User (ARPPU)

We define Average Revenue per Paying User (ARPPU) as the total revenue attributed to in-game purchases during a given time period, divided by the number of months in that period, and then divided by the Average MPU for that period. We believe that ARPPU is a useful metric to describe monetization.
