Apes can understand some things more quickly than human, one or two of them have learnt a few words. But they can not join words to make sentences. They can not think like us because they have no language. Language is a wonderful thing. Man has been able to build a modern world because he has language.

Article: There is a unique place where deserted factories have been transformed into a lively artistic zone - where the city's tradition and heritage meet with cutting-edge art and fashion. This is Redtory. Located at Yuancun Si Heng Lu, not far from the Pearl River of Guangzhou city, Redtory is a creative cultural and industrial zone made up of more than 30 old buildings - mostly red-brick ones. Back in 1956, it used to be the biggest canning factory in China. The factory produced the Can Dace with Black Bean Sauce, an iconic food product in the last century, well-known throughout south-east Asia. After the local government's industrial structure reformations, the canning factory moved away and the workshops were left deserted. There was nothing left but memories in well-preserved Soviet-style buildings. Not long after the noise of the running machines was gone, posters of advertisement and art were found hanging on the wall in the area. To enrich the cultural and artistic life of the people in Guangzhou, the abandoned factories reopened in 2009 - displaying art, fashion and culture of different forms. Redtory is home to more than 40 establishments including art galleries, themed restaurants and design studios. Large international cultural exchange activities, art exhibitions and seminars are often held here, attracting hundreds of thousands of visitors every year. Meanwhile, waste materials have been used wisely instead of being thrown away. For instance, some installations standing around the area are made up of the rusty machines or components from the old canning factory. The shabby and nostalgic appearance combined with fashionable and artistic features makes Redtory uniquely attractive. That may be the reason that Redtory is considered the holy land for young art-lovers in Guangzhou.
