	In ~~202x~~, the name of the historical constellation ~~"xxx"~~ ~~was~~ ~~suggested~~ to be ~~used~~ for ~~one~~ of ~~the~~ ~~stars~~ in ~~this~~ ~~constellation.~~ ...		In 2025, the name of the historical constellation Tiān Sì (Heavenly Quadriga, 天駟) was proposed for a star in its region, with discussion focusing on γ Cassiopeiae.

			On November 12, 2025 adopted the name Tiansi for γ Cas (27 Cas, HR 264, HD 5394, HIP 4427). γ Cas is a multiple system, and the name specifically refers to the massive primary star γ Cas Aa, which is a B0.5IVe star. The star is a famous eruptive variable, indeed the prototype of the γ Cas class, whose magnitude has varied historically between about magnitude 1.6 and 3.4. In recent years, the mean Johnson V magnitude has been around 2.17 (Smith & Henry 2021).

	Given the intimate cultural association between Tiansi and Wangliang, the two must have been conceived simultaneously. In their earliest stage, however, they might be regarded as distinct constellations, as recorded in the ''Tianguan shu'' (Book of Heaven Officials, 天官書). Only later, in the ''Shishi xing jing'' (Shi’s Star Canon, 石氏星經) later , were they formally unified into a single constellation under the name [[Wang Liang]]. Nevertheless, even long after their amalgamation, tradition continued to recognize the leftmost four stars of Wangliang as the “Quadriga” and some star map explicitly marked them as Tian Si.
