After conducting research, I found that the contact phone number of Xi’an Art Center (西岸艺术中心) is not publicly available. As a private cultural institution, it may not have made its contact information widely known to avoid unnecessary inquiries or solicitations.
If you need to get in touch with them, your best bet might be to try contacting their official website, social media platforms, or visit the center’s physical location (if you’re in Xi’an) for more information.
