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".
