The star name "Chow" is already in SIMBAD, so the WGSN should adapt it. However, the correct spelling in Pinyin Chinese would be "Zhou".

Etymology of the term

Since the Han dynasty, the number of stars in the Tianshi (Celestial Market) were fixed at 22, with each star representing a different state or region. The names of these states mostly originated from the Spring and Autumn （770 BCE - 476 BCE） and Warring States (475 BCE - 221 BCE) periods. The name "Zhou周" comes from the Zhou dynasty (1046 BCE - 256 BCE), which established a powerful state after overthrowing the Shang dynasty and enfeoffed many vassals. However, after the fall of the Western Zhou (1046 BCE - 771 BCE), the Eastern Zhou (770 BCE - 256 BCE) moved the capital to Luoyang, and their power gradually weakened. The vassals grew stronger and no longer recognized the Zhou's authority, declaring themselves kings and reducing Zhou's territory to a small area. Thus, in the Tianshiyuan, Zhou did not hold a transcendent position but was on par with other regional vassal states. The Tianshi, consisting of 22 stars, was formed at the Western Han (202 BCE - 8 CE) period, with star names changing before the Tang dynasty. However, since the establishment of Tianshi, Zhou (identified as Bet Ser) has always been one of the stars in the Celestial Market and has remained so for approximately 2000 years.

At least these six papers already used the name (although in old spelling) which shows its acceptance.

The word is simple, short and easy - even for people who don't know Chinese.
