National Library of China
All current editions of the "Lingshu" are based on Shi Song's edition from 1155. The earliest extant edition was made in 1339 and 1340, under the Yuan dynasty, by a publishing house called the Gulin shutang . One copy of this edition is still preserved at the National Library of China (Guojia tushuguan ) in Beijing. The Gulin shutang edition was the earliest known joint edition of "Lingshu" and "Suwen".
