The history of Kyeezees, a.k.a. Burma Bells, is complex and deep. Below is an excerpt from Far Cathay and Farther India (1893) by Alexander Buxton MacMahon, which shows how meaningful and valuable the kyeezee has been. From getting back a captive, to an item to salve the pain from being jilted by your lover, the kyeezee was there.

"Their passion for the possession of kyeezees is so pronounced that it is said instances are by no means rare of their bartering their children and other near relations for them, in subservience to a superstition that the deep-sounding note of these monotoned instruments propitiates the Nats and averts evil from themselves. In the settlement of serious quarrels, or in the redemption of captives, the in demnity with them always takes the shape of a kyeezee, with buffaloes and pigs as a make weight, just as in Western countries a concession of territory or perhaps some men-of-war is insisted on. In their social disputes also it forms an important feature, for according to Dr. Mason a girl who has been jilted can claim from her false lover a kyeezee for her body, another for her head, and a gong to cover her face for shame."
