I would like to ask if Guangdong Travel Guangdong Wonderful's "Guangdong Travel Ticket Postcard Album" can use this ticket postcard to enter the attractions for free? Thanks

Yes, but it is free if you bring one more person who needs to buy a ticket.

The postcard uses a real-name system. Before arriving at the scenic spot for use, you must fill in your name and ID number on the anti-counterfeiting verification page of the ticket. The scenic spot can verify your usage. If the ticket postcard holder brings one or more adult companions (including one), the ticket fee will be waived for the holder, and the companions will receive a 12% discount on tickets. Children's tickets will be purchased according to the regulations of the scenic spot; ticket postcard holders are If you do not travel with others, you can enjoy a 50% discount on tickets; after the Guangdong travel ticket postcard is mailed, the recipient of the postcard can still enjoy a 12% discount on tickets when traveling to participating attractions with his or her ID card and postcard.
