A new trend in China's trade-in market is the rising popularity of large and smart appliances, said the manager of a local home appliance store in southwest China's Guizhou Province. [Sound_bite] Ding Mingwei, home appliance store manager: "Thanks to the trade-in program, our overall sales have doubled compared to the previous years. Sales of large-screen TVs, large built-in refrigerators, washer and dryer sets, whole-house water purifiers and other appliances that enhance quality of life have increased by about 20 percent." [Voice_over] Data shows that smart appliances, like robotic vacuums, made up a significant portion of the trade-ins in the first half of the year, with sales for the device up 92 percent compared to last year. China has issued more than 32 billion U.S. dollars of ultra-long special treasury bonds so far this year to support the trade-in program.
