The Yingya Shenglan, written by Ma Huan and published in 1451, is a book about the countries visited by the Chinese over the course of the Ming treasure voyages led by Zheng He.

[2] Some time after 1424, Ma Huan introduced the posthumous title of the Yongle Emperor, who had recently died, to the foreword.

[6] Guo Chongli, with the help of his friend Lu Ting-yung, successfully sought out Gu Po to write the afterword.

[7] For instance, the Columbia University Libraries in New York houses a copy, but there are indications that the copyist availed themselves to other documents as it contains the foreword, poem, and afterword, has corrected readings, and adds few additional words that do not appear in the earlier version.

[9] Manuscript copies of the version can be found at the British Museum in London and the sinological institute in Leiden.

[7] The version was also published in chapter 63 of the Jilu Huibian (circa 1617), comprising 22 folios, and was incorporated in various other collections.

[7] The Shengchao Yishi (勝朝遺事), published by Wu Miguang (吳彌光) in 1824, contains a version of the Yingya Shenglan.
