Win alk Walking into All Sages bookstore in northwest Beijing, you enter a different world. Here is not the collection of speeches by China’s leader Xi Jinping that greets visitors to state-owned bookstores – rows of covers with the same faces, the same benevolent smiles. Liu Suli, the founder of All Sages, served 20 months in prison for his role in the Tiananmen Square protests of 1989. His shelves are filled with the works of independent thinkers: economists and political scientists, historians and legal scholars. The potential market may be bigger than it was during the preparations for Tiananmen. China’s liberals are becoming more numerous than ever, says Mr. Liu.
