I’d be happy to help!
To answer your question, the Alpha tickets you’re referring to are likely the “Alpha Pass” or “GZTA Alphapass”, which is a special ticket that allows access to the observation deck of Canton Tower (广州塔) in Guangzhou.
The answer is: No, buying only an Alpha ticket does not grant access to the top floor of the tower. You would need to purchase a separate ticket for the observation deck or take part in one of their guided tours that include this privilege.
I hope this helps!
