중국 새해연휴 1억2천만명 대이동••• '스모그 난민' 도시 탈출
Chinese people are starting the new year chocking on smog.
Despite Beijing's claims of making efforts to reduce air pollution, heavy smog alerts have been issued for the northern parts of the country..
The air was so toxic in some areas that it even residents took off to spend their New Year's elsewhere far from home.
Lee Ji-won has the full story.
With the smog in the northern parts of China getting worse by the day,... a smog alert has been issued in over 60 cities... and a huge number of residents spent their New Year's away from the area.
According to China's environmental protection ministry, red alerts have been issued for 24 cities.
That's the highest level in China's four-tier pollution warning system and at that level, factories, schools and construction sites are closed.
On top of that, the next alert levels of orange and yellow have been issued for 37 cities,... including the capital of Beijing.
"Nobody likes smog. Smog has negative effects on people's emotions and we're all feeling very bad about this."
"I feel so depressed. I have a child, but I can only keep him at home and he can't even go out to get any sunshine. This really worries me."
Reports say the bad smog can be attributed to an increase in violators of a five-year plan aimed at reducing air pollution.
The ministry said the cold weather was also a factor, as more coal is burned for heating, in addition to the already poor atmospheric circulation in the winter.
As a result,... some 120-million residents of places in northern China spent their three-day New Year's holiday in the southern parts of the country, including Sanya, which saw a 7-point-7 percent increase in tourists on the first day of the new year,... compared to same time last year.
The Chinese government is currently working to alleviate the pollution by dispatching inspection teams to factories, but the ministry says current air pollution levels are expected to last until Thursday.

Patients taking Viagra are less likely to suffer a heart attack, new research claims.
Men taking the impotence drug were found to have a lower risk of having a heart attack or dying from heart failure than those not on the medication.
The findings mean Viagra could soon be used to treat hundreds of thousands of heart failure patients and even prevent fatal heart attacks, scientists say.
Experts from the University of Manchester studied 6,000 diabetic patients who had been given Viagra to treat erectile dysfunction.
The drug relaxes muscle cells in the blood vessels supplying the penis, allowing more blood to flow there.
This increased blood flow increases the likelihood of getting an erection.
Given the increasing reports of deaths in which the use of Viagra may be implicated, clinicians need to exercise caution when advising their patients with heart
Experts believe a key ingredient in Viagra called PDE5i, which relaxes blood vessels, also prevents damage to heart cells.
Heart failure is caused by the heart failing to pump enough blood around the body at the right pressure.
It most often occurs because the heart muscle has become too weak or stiff to work properly and is usually treated with medication which supports the heart.
Despite diabetics being prone to heart problems, the study participants did not suffer as many incidents as similar patients not on the drug.
