Hundreds of millions of people are expected to travel within China during the country's week-long National Day holiday that began on Friday.
Domestic trips are proving popular during the holiday, which runs through next Thursday, as the global coronavirus pandemic makes overseas travel difficult.
A major trip reservation website estimates 650 million domestic trips will be made during the holiday. That's a recovery to about 80 percent of the level seen in 2019, prior to the pandemic.
On Friday, people going on vacation or heading back to their hometowns were seen entering a train station in Beijing.
Universal Studios Beijing, which opened on September 20, was crowded with young people and families.
The operator of the theme park says tickets for the holiday period are almost sold out and that people without tickets are being denied access as an antivirus measure.
A female university student from Dalian said she is very satisfied, as she has been looking forward to the opening of the park.
She said she has no concerns as strict antivirus measures are being taken.
