在外打工的四川人担忧家庭安危(Migrants Worry Over Family In S

　　shanghai — li suyue left sichuan two years ago and traveled the 1,000 miles here for a job in a small restaurant. now, days after the earthquake that struck her province, she is distraught, unable to go to work. she constantly tries to call home.

　　“the day before yesterday, my father called and said they are o.k.,” she said. “but now i cannot reach them again. my mind is totally a mess.”

　　for three decades, china’s explosive economic growth has been fueled by its enormous pool of migrant workers, perhaps as many as 200 million people who construct roads and buildings, lug coal, fire steel and operate the assembly lines that churn out much of the world’s toys, clothing and electronics. among them are a huge but uncounted group from sichuan — estimated at somewhere between 6 million and 20 million. like ms. li, they left to find work in wealthier, coastal, regions — and are now tormented by the reports of the worst natural disaster to hit the country in more than 30 years.

　　their frantic efforts to get word of their families are thwarted by downed telephone lines and disrupted cellular phone base stations. the surge in calls has locked up functioning lines.xiao fuhua, 33, whose wife and three children are in liangshan, an area in southern sichuan province that is not supposed to be hard hit, said he had been unable to reach his family at all.

　　“i was told there was no signal in sichuan because of the earthquake,” said mr. xiao, who earns about $120 a month as a construction worker in tianjin, east of beijing. “i heard a lot of bad news from tv. i hope they are o.k. it’s said that the earthquake in liangshan is not very big, but i’m still worried.”

　　no area of china has supplied as much labor as sichuan, a fertile, mountainous region in the country’s southwest, home to pandas, bamboo forests, spicy cuisine and some of the country’s most difficult terrain, stretching west into the tibetan plateau and north toward the arid lands of gansu province.

　　sichuan also sits along one of asia’s biggest tectonic faults, making it prone to devastating earthquakes.when the chinese leader deng xiaoping, a native of sichuan, began pushing the country’s economic development in the 1980s, the government allowed poor people from farms and rural areas to move to big cities and coastal areas to work at factories and construction sites.

　　millions picked up and left sichuan. many have lived for years in cramped dormitories or temporary construction barracks, separated from their families, hoping to make enough to return home.li bo, 21, came to shanghai in 2004. he is from the city of mianyang in sichuan, northeast of the earthquake’s epicenter.his mother is safe, he says, but most of the rooms in his house have collapsed — the house the family spent thousands of dollars improving.

　　but he frets over a report from a relative that a huge lake called the bai shui has completely disappeared, apparently sucked down into the earth’s crust after the quake. could it be true, he wonders.“maybe the lake has disappeared forever,” he said. “this would be a disaster. the people would have grain but no water to boil things.”zhang shanghai, another 21-year-old sichuan resident working in shanghai, said he had reached his family. they had not yet heard from an uncle who had been working in a mine, and they were still tortured by tremors.“when i called my family yesterday, i heard the sound of heavy rain,” he said. “my uncle told me aftershocks are occurring every half hour and that his legs are shaking all the time, even in the safe periods.”
