①When we talk about Chinese handmade paper，you probably think of Xuan paper. However，there are different kinds in different places，and Lianshi paper from Fujian is one of them.
②Going back 400 years，Lianshi paper was made by hand using bamboo. According to Fujian Daily，Lianshi paper weighs only 19 grams(克)every square metre，but it is strong. Thanks to this，Lianshi paper was listed as a provincial intangible cultural heritage in Fujian in 2008.
③Deng Jinkun，54，has been learning to make Lianshi paper for 30 years. He said making Lianshi paper has 72 steps，including cutting bamboo，soaking(浸湿)，making pulp(纸浆)，and drying. What makes it stand out is its bleaching(漂白)technology. “In May each year，bamboo is cut off，and soaked in lime(石灰)twice. The bamboo is then heated at a high temperature. After that，it's bleached on the mountain for four months，” Deng said. “The natural bleaching process makes it white，” he added.
④Besides carrying on traditional art，Deng also brought in new ideas at the same time. Traditionally the pulp is collected using a wooden shelf held by two people. “Our Lianshi paper needs only one person as we use strings(细绳)to hang one side，” Deng said.
⑤When they heat the paper，the baking wall is also special. According to Deng，other places use lime to make the wall. “After a trip to the University of Science and Technology of China in 2018，I decided to use a special kind of clay to make the wall so that it lasts longer，” he said. After it is built，the baking wall can be used to make paper for 40 years.
