Tens of thousands of people - Han Chinese and Uygur - are streaming out of Urumqi even as authorities try to restore a semblance of normality amid a massive show of force following Sunday's ethnic violence, which left 156 dead and more than 1,000 injured. Dishevelled passengers thronged the city's long-distance bus stations and train station, desperate for a ticket out of the once-booming industrial centre, capital of the Xinjiang Uygur Autonomous Region . Han and Uygur mingled together - something that has become rare since Sunday's riots and the angry protests which followed them. One bus station director, who gave his name as Ask, said 200,000 students alone could take buses home this week. Outside the train station, a miner from Anhui province said 12 of the 20 colleagues who had come with him to Urumqi for work had left in the wake of the riots, and he would not be back. 'At home we make at most 150 yuan (HK$170) a day and here we get 200 yuan. But [this place] is not as peaceful as home,' he said. A Uygur going back to Kashgar agreed. 'I just come here to make a living. I still have parents at home [in Kashgar] to support. It's not worth risking your life for a job.' Most Uygurs are heading to southern Xinjiang to take refuge in cities such as Kashgar - where they are still in the majority; three-quarters of Urumqi's population is Han. Migrant Han workers are returning to the inland provinces from whence they came. Urumqi, a city of 2.3 million, was mostly quiet after authorities sent in thousands of troops and riot police threw a cordon around Uygur neighbourhoods. Nevertheless, sporadic violence continues, and a Han man was found killed early yesterday. Most parts of the city are now deemed safe enough to travel. Queues have been forming at bus stations since Wednesday morning. Bus tickets had sold out by noon yesterday, and scalpers were making a fortune - a ticket to Kashgar that would normally cost 170 yuan was selling for 400 yuan, equivalent to a month's salary for some people. Ask, the station director, said they had put on an extra 10 buses for Kashgar, on top of the usual 14, but that 'the long waiting and overcrowding are unavoidable'. Twenty-two-year old Ao Zi Gul, a technology student, said: 'I prefer to wait for the promised extra buses since I don't have money to buy the 400 yuan ticket [from scalpers].' The authorities appeared happy to help the students leave, summoning hundreds of extra buses from across the region to take them away. Witnesses said Sunday's violence followed a protest called by Uygurs over a brawl last month at a Hong Kong-owned factory in Shaoguan, Guangdong, which left two Uygurs dead and 118 people, most of them Uygurs, injured. Uygur students attending colleges in Urumqi are believed to have played a big part in Sunday's protest, and to have used the internet to spread stories about the ethnic clashes which followed. A Xinhua report said Xinjiang transport authorities had arranged 108 buses and sent 3,850 students home by late yesterday. A teenager who had just graduated from a city high school and who gave her name as Wang said now was the perfect time to head home. She was among the first to arrive at one of the bus stations yesterday, but still found a long queue ahead of her at the ticket booth. Tickets to her hometown, Turpan in eastern Xinjiang, had long sold out, but people were still hanging around in the hope the government would help arrange extra buses. 'My parents were worried to death,' she said. 'They told me to take a bus home as early as I can.'
