BEIJING, May 5 (Xinhua) -- With many tourist sites across the country reporting record numbers of visitors during the ongoing Golden Week holidays, travel accidents resulting in injuries and deaths have also been frequent in the past few days.

The National Holiday Office, a government agency established for Golden Week holiday operations, has warned local governments, tourist companies, resort sites and tourists as well, that they must take precautions against accidents.

On the early Friday morning, a group of nine senior citizens climbed the Fragrance Mountains in eastern suburbs of Beijing, but came back with eight alive. A 64-year-old man died of a heart attack. Rescuers said poor mobile phone signals in the remote areas and darkness made it harder for them to reach the man before it was too late.

Also on Friday, a man was drowned in the One-Hundred-Flower Valley, also a popular tourist destination in southeastern Beijing.

The same day, a group of four daring young people trekking the Yunmeng Mountains in suburban Beijing got themselves lost twice. For the first time, they happened to come across a park staff and got helped once. And the second time, they were lucky to be rescued by the patrolling police near the park.

On May 2, an avalanche in Yunnan killed 2, injured 7. The same day, an aero boat and yacht collided at a waterborne recreational center in Nanjing, and seriously injured a 13-year-old girl.

The National Holiday Office said in a circular seen by Xinhua on Saturday that many expedition-inspired tourists are prone to accidents when in remote areas or out of the periphery of parks and tourist resorts. Tourists who are obsessive with adventures during the holidays "should be well prepared and instructed by professionals," it said.

The rising number of private cars in Chinese cities has given rise to the new generation of adventurers during holiday time.
