An investigation is underway.
Railway stations, expressways, and airports across China saw a travel peak on Saturday, the first day of the 3-day Qingming Festival holiday.
Official statistics show that the number of passengers nationwide reached nearly 12 million on Saturday, up 13 percent year on year.
Over 500 trains were added to help ease the travel pressure.
Road traffic also saw a peak, with volume on China's ten major expressways up 14 percent from the same period last year.
In addition, major airports in Beijing, Shanghai, Guangzhou coped with a sharp increase in passengers.
Overseas travelers helped to swell passenger numbers, with Thailand and the United States among the most popular destinations.

China's meteorological authority has continued a blue alert, the lowest level in a four-tier warning system, as rainstorms will hit most parts of the country's southern regions.
Hunan, Jiangxi and Zhejiang provinces will see torrential rains, strong winds, or even hail on Sunday.
The rainfall is expected to reach 90 millimeters.
Mountain torrents, mud-rock flows, and landslides are likely as a result of the heavy rains.
A Chinese firm has developed the country's first 300-megawatt nuclear reactor cooling pump.
The developer, Harbin Electric Corporation, says the cooling pump has passed state appraisals of the China Machinery Industry Federation.
The cooling pump has been tested for 200 hours of continuous operation under automated high-temperature and high-pressure conditions.
Previously, China depended on imports for key components of pressurized water reactor nuclear power plants.
The country aims to raise its installed nuclear power capacity to 58 GW with an additional 30 GW under construction by 2020.
Australian authorities have confirmed that another piece of debris, found in Mauritius, will be examined in connection to the disappearance of MH370.

Experts have confirmed that two pieces of debris found in Mozambique were "consistent" with panels from a Boeing-777 jetliner therefore are "almost certainly" from the missing flight.
Flight MH370 disappeared on March 8, 2014, enroute from Kuala Lumpur for Beijing with 239 people on board. Most of them were Chinese nationals.
The European Union is to unveil plans to overhaul its asylum system following a controversial migrant deal with Turkey.
The current "Dublin rules" place a huge burden on migrant entry points such as Greece, as they say refugees must claim asylum from the first country they arrive in, and should be returned there.
The system has been rendered effectively obsolete by the huge flow of humanity drawn to wealthy Germany by Chancellor Angela Merkel's open door policy for Syrian refugees.
The European Commission is set to lay out "possible options" before setting out a formal proposition to reform the asylum system later this year.
Experts from Cuba and the United States have held a discussion in Washington regarding health care cooperation.
The Cuban Foreign Ministry says the cooperation will range from prevention and treatment of communicable diseases such as Zika and dengue, to chronic illnesses like cancer.
The health experts have also identified other topics of interest, including medical research and mental health.
The health talks follow the US president's historic visit to Cuba in March.
U.S. Republican Presidential Candidate Donald Trump has railed against President Obama and the Iran nuclear deal.

He also criticized Belgium for not performing background checks on immigrants.
The Republican presidential candidate was speaking at a rally in Eau Claire, Wisconsin.
