The originality of the book design originates from the packaging of Pu'er tea bricks. The natural bamboo shells are gently wrapped and spread around the world through the ancient Tea Horse Road. So this time we also hope that through the rustic design technique, the book as a whole is a cake of tea, and several old Pu'er tea leaves on the cover spell out the font 'meet Pu'er'. We hope that through this cake of tea, we can bring readers into Pu'er tea. The world, a cake of tea bricks, allows you to taste the development of Pu'er.
