Workers assemble a model of a transforming alien robot - based on the Transformers entertainment franchise - in a factory in Shengjin town, Zhangqiu, a city in East China's Shandong province, March 27. Liu Xianhui, a farmer in Zhangqiu, leads a team of 11 farmers to make the products, with used tires or other materials often purchased from second-hand markets. They have sold a total of 8 of the more than 30 models they have made, with the most expensive selling for over 100,000 yuan. [Photo/Xinhua]
