Excuse me, where is the download and tutorial of opera Hotel Management System?

This is an engineering software. Opera hotel management system can't be bought by hundreds of thousands of ordinary small enterprises. Unlike the front desk used by ordinary low-level hotels to book hotels, you can find them by the way. In the eyes of outsiders, opera hotel management system may not be very important, but it may be related to the life and death, rise and fall of an enterprise, which is very important.

This software is difficult to find and download on the Internet. I tried to find it, but I still couldn't find it. If the landlord wants to experience it, he can work at the front desk of a large international hotel, which is usually used.

The website with the download operation manual is/download/han333/5646813.
