Welcome friends who are interested in electronic paper books to the electronic paper book forum to communicate with each other. Baidu can search the e-paper book forum or the McDull e-paper book website containing mydoo. I hope you don't take it personally. I just want to gather more fans of electronic paper books to discuss and promote the development of this new industry born for environmental protection.
