When the Fuxi-style qin came to the CUHK Library, it attracted the attention of qin experts in Hong Kong.  Its snake-like crack pattern, called duanwen (斷紋), informed its antiquity.  Although there was still crack pattern in the style of da shefu (大蛇腹) on the surface board, the patterns at the sides and the bottom board were almost gone.[3]  Qin experts in Hong Kong, including Mr. Shum Hing Shun, Mr. Sou Si Tai, Dr. Tse Chun Yan, and Professor James Watt, examined the qin in April 2012 at the Chung Chi College Elisabeth Luce Moore Library (Fig. 1).  There was a hole on the surface board, which was not a common structure of qin, so Mr. Sou Si Tai filled the hole (Fig. 2).

In June 2012, the qin underwent endoscopy by Professor Francis Chan of Faculty of Medicine.  The endoscopy result informs that two lines of text were written with cinnabar on the surface board inside the qin belly: “大唐開元二年蘭庵主人得梓材古琴雷威重斲” (Video 1).  The text says that the owner of lanan got this catalpa qin in year two of the Kai Yuan era of the Tang dynasty and itwas repaired by Lei Wei.

After an investigation of the qin, Shum wrote a report . Although the cinnabar text suggested that the qin underwent a repair in the Tang dynasty, Shum estimated that the qin was built in the early Ming dynasty with reference to its size, shape, and wood.[5]  He commented that the text might have been added by one of the early repairers and is a misleading statement.  The qin might have its last major repair not earlier than the late Qing dynasty.[6] 

In May 2018, the qin further underwent a CT scanning.  The results were inspiring.  With the slides from the CT scanning, which were the transverse section of the qin (Fig. 3), the Library further explored the secrets hidden inside the qin using the software OsiriX MD, a medical images viewer. [7]  The thickness of the qin‘s wood became visible (Fig. 4).  Two coins (Figs 3d, 3e, 4d, and 4e) and the filled hole (Figs 3f and 4f) were found at the neck region of the surface board.  The coronal section shows that they align with each other.  Furthermore, in addition to a passage of text being engraved beneath the “dragon pool” (龍池) of the bottom board, the possible names of the qin were discovered above the “dragon pool” at similar levels of section.  These results will be discussed in the other sessions of this report.
