1. First, open the Moutai anti-counterfeiting traceability system client on your mobile phone, and you will see the interface as shown.

2. Then an anti-counterfeiting traceability page will appear. In this page, follow the prompts to align the NFC sensing area on the back of the phone with the RFID bottle label on the top of the Moutai bottle cap.

3. At this time, if the Moutai is authentic, the page will prompt that the query is successful and display the details of the Moutai.

4. If the page prompts "Query failed", it means that the bottle of Moutai is pirated, that is, fake.
