	Huá Gài (Canopy of the Emperor, 華蓋) is a Chinese asterism consisting of sixteen stars, divided into two parts: seven stars forming the ''Huá Gài'' (“Canopy”) proper and nine forming the ''[[Gang\|Gàng]]'' (“Shaft”). The configuration of this asterism varied considerably over time. In its earliest form, it was located within the modern constellation ''[[Cepheus]]'', but later versions shifted its position toward ''[[Cassiopeia]]'' and ''[[Camelopardalis]]''. The asterism originated within the Gan school during the Han dynasty, around the first century BCE.

	The term ''Huá Gài'' originally denoted an ornate ceremonial canopy used in the carriages and processional retinues of ancient emperors. Those used by ministers were called simply ''gài'' (“canopy”) or ''sǎn'' (“umbrella”). Although the canopies differed in form and structure, they could be generally classified into two types according to the shape of their handle: the “straight canopy” (''zhí gài'') and the “curved canopy” (''qū gài'').<gallery widths="200" heights="200" perrow="5" caption="Ancient Canopies">		The term ''Huá Gài'' originally denoted an ornate ceremonial canopy used in the carriages and processional retinues of ancient emperors.

	However, this account is likely legendary, as no archaeological evidence of a carriage canopy with a curved handle has yet been found.

	Carriage canopies were generally straight-handled, while those used in ceremonial processions often had curved handles—likely to allow the attendant holding the canopy to stand slightly apart from the dignitary beneath it. Numerous Han to Tang dynasty murals depict emperors or celestial beings sheltered under a curved canopy. The earliest configuration of the ''Huagai'' asterism appears to mirror precisely this type of canopy structure.

	Several ancient star maps preserve depictions of ''Huagai''. The earliest known image appears in the ''Cheonsang Yeolcha Bunyajido'' (''Charts for Celestial Branches and Field Allocations'', 天象列次分野之圖). In this version, Huagai is positioned within ''Cepheus'', differing from all later maps produced after the Tang dynasty. In this early chart, the asterisms ''Wǔ Dì zuò'' (“Seats of the Five Emperors”, 五帝內座) and ''Liù Jiǎ'' (“Six Jia”, 六甲) are shown directly beneath ''Huagai'', precisely matching the description in the ''Gān’s Star Canon'' (Gān shi xing jing, 甘氏星經). Later maps, however, no longer conform to the textual record.		Several ancient star maps preserve depictions of ''Huagai''.

	A record of a meteor observed in 512 CE reports that it passed through the region of ''Huagai''; its trajectory corresponds only to the position shown on this early chart, while the locations drawn on post-Tang star maps do not align.<ref>[https://www.raa-journal.org/issues/all/2024/v24n12/202412/t20241216_278177.html] Bo-Shun Yang and Susanne M.

	The most striking comparison lies in morphology: only the ''Huagai'' depicted on this earliest star map preserves the authentic early form of a curved-handled imperial canopy and its shaft (''gàng''). In contrast, later depictions from the Tang dynasty onward exhibit noticeably distorted shapes, reflecting a departure from the original symbolic design.
