When you use the MazuHost - Automated Management Center to register your new domain name, please fill in English for all your informations. This includes your name, address, company name, contact number and email.
Because the current registered domain name API of the world, it does not support other language contact informations. if you not use English language, it is easy to cause failure.
But I apologies for any Inconvenience.
In addition, some domain name registrations may also need to provide additional information, such as: company registration, proof of identity, etc.
