The name Θῖναι, Strabo, Σῖναι, Ptol., Τζίνιτζα, Kosmas, did not obtain currency first from the founder of the dynasty Tsin; but, long before this, Tsin was the name of a feudal kingdom in Shensi, one of the western provinces of the Sinese land, and Feitsa, the first feudal King of Tsin, began to reign as early as b.c. 897.

In the earlier chapters uncouth proper names are reduced to a minimum, but the Index refers by name to specific places and persons only generally mentioned in the earlier pages. For instance, the states of Lu and Chêng on pages 22 and 29 : it is hard enough to differentiate Ts‘i, Tsin, Ts‘in, and Ts‘u at the outstart, without crowding the memory with fresh names until the necessity for it absolutely arises. […] CHOU: at first a principality in South Shen Si and part of Kan Suh, subject to Shang dynasty; afterwards the imperial dynasty itself.TS‘IN; principality west of the above. When the Chou dynasty moved its capital east into Ho Nan, Ts‘in took possession of the old Chou principality.TSIN : principality (same family as Chou) in South Shan Si (and in part of Shen Si at times).TS‘I: principality, separated by the Yellow River from Tsin and Yen; it lay in North Shan Tung, and in the coast part of Chih Li.TS‘U : semi-barbarous principality alone preponderant on the Yang-tsz River.]
