姓 ("Little + Surname") is the standard friendly Chinese address for a younger or junior colleague.
姜 (Jiāng) is a common surname tracing back to the legendary Yan Emperor (
炎帝) and the Zhou-dynasty strategist
姜子牙 (Jiang Ziya). The character
姜 also means "ginger," but as a surname only the reading and origin matter — no ginger pun intended.
