domain redirection

Hello, I have a concern that when I create subdomain 1, and 2 and ... then I will point to the sub-websites and when users enter the subdomain web, they will be redirected to the main website. Will it affect SEO? And is it possible to automatically redirect when clicking on the subdomain to the official website? Thank you.

there's no reason for users to get redirected to root domain (unless you manually and purposely make that redirection). And no, if you don't do redirections the subdomains won't affect your SEO, google treats each domain (domain.com) and their subdomains (sub1.domain.com, sub2.domain.com, etc) as separate websites.

So, if you install a website onto each subdomain and never redirect those websites to the root domain google will consider you have multiple websites. But this is a simplistic view. If you have a membership or ecom site and your subdomains have specific functions then sure, google will view the subdomains as part of the main site (domain.com)...

But anyway, I don't think that I fully understand what you're asking, so I gave you general info. Please use google translate to convey your ideas more clearly as I really scratched my head trying to figure out what you're asking

If you redirect all subdomains to the main site, it could affect your SEO because Google might see it as duplicate content or not index the subdomains properly. To avoid negative impacts, it’s best to have unique and useful content on each subdomain.
As for automatic redirects, it's possible, but if you overuse them, it could confuse search engines and users. So just be cautious!
Hope you well!

I suggest that instead of creating a subdomain and pointing to the subsite, whoever visits it will be redirected. Then remove the subsite. If anyone visits the subsite, they will be immediately redirected to the main site. I haven't tried it yet, but whether it affects SEO.
