Can I go back to Meishan Renshou during the May Day holiday?

Yes

Meishan CDC reminds you to pay attention to the following matters: anyone who enters (returns to) the territory from outside the province should register at the destination in advance, provide negative proof of nucleic acid test within 48 hours, check the health code and exchange itinerary card, and cooperate with scanning the "entry code" after returning to Sichuan.

Personnel entering (returning) eyebrows outside the province must scan the "Code of Special Place for Inspection in Sichuan" (referred to as "Entry Code" for short) through "Sichuan Tianfu Health Link" at each inspection point. When scanning "Enter Code", there will be a pop-up window. Persons entering (returning to) eyebrows need to go to the nearest medical institution for free nucleic acid testing within 24 hours. If the nucleic acid test result is negative, the temporary pop-up window will be automatically released after 24 hours. If the nucleic acid test result is not found for more than 36 hours, it will be turned into a temporary yellow code, and if the nucleic acid test result is negative after/kloc-0 times in the province, it will be automatically turned into a green code.
