Xinhua Headlines: 70 years on, China's Xinjiang embraces future with vitality, stability

Xinjiang's progress was made possible by the peaceful liberation of the region, the 70th anniversary of which will be celebrated Wednesday.

The region has seen improved living standards for its people and as proof of the general stability and sound development momentum, not a single terrorist attack has occurred in Xinjiang over the past three years.

URUMQI, Sept. 24 (Xinhua) -- The city of Shihezi is a sprawling green area home to 670,000 people. As September ends and the harvest season arrives, farmers are ready to reap the large cotton fields in the city's suburbs.

Shihezi, about 150 km northwest of Urumqi, is a young city established in the 1950s in Xinjiang Uygur Autonomous Region. It is one of the nine bustling cities that has risen from the bleak Gobi Desert.

While about 1,600 km away in the southwest, Kashgar, an ancient Silk Road city, maintains the charm and authenticity of a 2,000-year-old town.

The contrasting landscape marks the vastness of Xinjiang, which covers about one-sixth of China's land territory, and epitomizes how Xinjiang has progressed both economically and culturally.

This progress was made possible by the peaceful liberation of the region, the 70th anniversary of which will be celebrated Wednesday. In 1949, the liberation struggle gained momentum across the country and the revolutionary struggle of the people of all ethnic groups surged forward in Xinjiang, Tao Zhiyue, garrison commander of Xinjiang, and Burhan, chairman of the Xinjiang Provincial Government, renounced their allegiance to the Kuomintang and welcomed in the First Army Group of the First Field Army of the Chinese People's Liberation Army (PLA), led by General Wang Zhen.

From then on, Xinjiang embarked upon a journey of increasing prosperity, unity and stability.

As proof of the general stability and sound development momentum, not a single terrorist attack has occurred in Xinjiang over the past three years.

SOCIAL DEVELOPMENT

In the years that immediately followed the peaceful liberation, Xinjiang's average life expectancy was 30 years. The figure reached 72.35 years in 2018. Now 25 million people live in 14 prefectures and cities in the region.

Before the liberation, most arable land in Xinjiang was seized by a handful of landlords, leaving very little to the majority of farmers. Serfdom existed in southern Xinjiang, where overlords owned their serfs from head to toe.

Samsak, a herder in Kashgar, owned nothing more than the clothes he was wearing when PLA soldiers liberated him. His name, meaning "garlic" in Uygur language, was given by his master. From the age of 17 to the age of 60, he had done nothing but herded sheep, yet he owned none of them.

Through a democratic reform that toppled the old system, ordinary people like Samsak received their own land and sheep and became masters of their own fate.

In 1955, the system of regional ethnic autonomy was implemented in Xinjiang, offering a further guarantee to the people of Xinjiang in exercising their right as masters of the country.

In 1950, Xinjiang only had 3,000 ethnic minority cadres. By 2018, the ethnic cadres made up 50.3 percent of the total in Xinjiang to reach 428,000, of whom over half are women.

Xinjiang has seen improved living standards for its people over the past seven decades. Public services, such as free health checkups for all, critical illness insurance, free preschool education for rural children, and housing projects for herders and farmers, have increased people's sense of fulfillment. Tap water, stable power supply and roads have been made accessible to herders who live in the most remote border areas.

During an inspection tour to Xinjiang in 2014, President Xi Jinping called for steadfast efforts to attain leapfrog development, while stressing efforts must be made to improve people's livelihoods and win the support of the people.

Living on the edge of Taklimakan Desert in Hotan, Tursuntoht Jume, 61, cherishes the tap water supply that was only recently installed in his home. "For half of my life, I had been drinking from the pond. Drinking directly from the tap, this makes me happier than anything else," he said.

Safe drinking water, among other things, is one criterion to gauge poverty relief efforts in Xinjiang. From 2014 to 2018, Xinjiang lifted over 2.3 million people above the poverty line, defined by a per capita annual income of 2,300 yuan (around 333 U.S. dollars) at 2010 prices. The poverty rate in the region is 6 percent. By next year, these remaining people are expected to be taken off the impoverished list.

VIBRANT ECONOMY

Spotless packaging lines are in full operation at a plant in Xinjiang Fruits Products Group Co., Ltd., based in Urumqi, the regional capital. Dried dates, walnuts and raisins produced in Xinjiang are sold across the country and overseas.

Thriving fruits, grain, cotton, and animal husbandry industries make Xinjiang the main agricultural region in China. It is the country's largest cotton production base.

The tourism, trade and manufacturing industries are also booming in the region. From January to August, Xinjiang received about 150 million tourists, which is close to the full-year figure for 2018. The region is expected to welcome over 200 million tourists this year, said Erkin Tuniyaz, vice chairman of Xinjiang.

Xinjiang's gross domestic product (GDP), which was 791 million yuan in 1952, soared to 1.2 trillion yuan in 2018, an annual growth rate of 8.3 percent. Per capita GDP was 49,000 yuan in 2018, yearly growth of 5.7 percent compared to 1952, statistics showed.

Since 2014, Xinjiang has seen 2,451 westbound trains, reaching out to 26 cities in 19 countries, exporting mechanical parts and laptops while importing products such as wine and grain. In 2018, Xinjiang's foreign trade volume was 20 billion U.S. dollars, 1,481 times the figure in 1950.

"Xinjiang plays an irreplaceable role in building the Silk Road Economic Belt. It must seize the historic opportunity, and integrate regional opening-up strategy into the country's efforts to build the Silk Road Economic Belt and open up to the west," President Xi said.

PRESERVATION OF CULTURE, HERITAGE

Abudubek Eskan, 42, often thinks of his teacher Jusup Mamay, a legendary singer of the Kirgiz epic Manas, who passed away in 2014 at the age of 97 in his hometown of Akqi County in Xinjiang.

Epic Manas tells the story of the hero Manas and his seven descendants in more than 230,000 lines. Manas singers are highly regarded by Kirgiz people for their good memory and narrative skills.

"The passing down of Manas depended solely on one master telling another face to face. Once the master dies, it is very difficult to pass down the art," said Eskan.

The government of Kirgiz Autonomous Prefecture of Kizilsu has accredited 100 people, aged from 20 to 70, to be Manas singers. They receive monthly government stipends to carry on the art.

"I'm teaching my 7-year-old son to sing Manas, I hope young people can bring new life to the art," said Eskan.

Xinjiang is a multi-ethnic region. Across the region, there are 24,800 venues for religious activities, including mosques, churches, Buddhist and Taoist temples, with 29,300 religious staff. People in the region enjoy freedom of religious belief. Efforts have been made to boost ethnic unity so they could be united together "like seeds of a pomegranate."

The family of Kurban Tulum is well-known in Xinjiang for their roles in promoting ethnic solidarity.

Kurban Tulum, a farmer from Hotan, was twice received by Chairman Mao Zedong. Now the extended family of Tulum has over 100 members.

Tohtihan Kurban, the eldest daughter of Kurban Tulum in her 90s, has spent her lifetime continuing her father's efforts. "Having gold and silver does not make you rich, unity and harmony between people is the true treasure," she said.

  1。溶剂和乳化剂用于清洁钢表面,以便去除油、油脂、灰尘、润滑油和类似的有机物质。但是,由于它们不能去除钢表面的锈蚀、氧化皮和焊剂,所以只能作为反政府行动的辅助手段。
 
  
 
  2.酸洗处理一般采用化学和电解法,管道防腐只采用化学酸洗,除氧化皮、铁锈和旧涂层外,有时还可作为喷砂后的后处理除锈。虽然化学清洗可以使表面达到一定程度的清洁度和粗糙度,但其锚固颗粒较浅,容易对周围环境造成污染。
 
  
 
  3.钢丝刷等工具主要用于钢表面的抛光,可去除疏松的氧化物、铁锈、焊接渣等。手动工具除锈可达到SA2级,电动工具可达到SA3级。如果钢表面牢固地附着在氧化铁皮上,工具的除锈效果就不理想,也不能达到防腐施工所需的锚索深度。
 
  
 
  4.喷雾除锈是一种高功率电机驱动的喷雾叶片的高速旋转,在电机的强离心力作用下,在P91合金管表面喷涂钢球、钢砂、铁丝和矿物等磨料。在磨料冲击和摩擦力的作用下,P91合金管不仅可以完全去除氧化、锈蚀和污垢,而且可以获得均匀的粗糙度。喷淋除锈后,不仅可以扩大管道表面的物理吸附量,而且还可以提高防腐涂层与管壁之间的机械附着力。因此,喷雾除锈是管道防腐的理想途径。一般说来,喷丸主要用于管内表面的处理,喷丸主要用于P91合金管的外表面处理。
 
  
 
  在生产过程中应严格要求有关除锈技术指标,防止操作误差对合金管造成二次损坏。去除刺绣后,合金管的外观会比去锈前光滑。合金管的除锈是钢管工业中常用的技术。
