How to get the experience service qualification of the Anti-Japanese War?

Any game will have its own experience clothes in the early stage, which is really a good choice for many players who want to try new things. So how can we get the qualification of experience service? It's actually very simple. If the official recruits some players with experience clothes to test the game, they will put a recruitment notice on the game official website. At that time, players can participate in activities by applying for jobs. If you apply, the requirements of each game are different, so be prepared early!
