Hello, @Jun_Sun
I am very glad to hear that you have decided to support the Cardano protocol by creating a pool. That is no small task. To get help you have already taken the first step (this topic). You could also reach out to @Alexd1985, he runs a charity pool, has vast experience and is always willing to help others.
As for getting delegators, my best advice is to support the community by taking initiatives. This is creating educational content, dedicating a portion of the rewards to some charity you identify with or to your own delegators. And last but not least, to allocate all the resources you have at your disposal to the creation of a single stake pool.
Maybe if you follow these little tips, then the following IOG bog post will be helpful to you as well.
Greetings.
Nápoles.
