Family Name: The surname 蓝 originates from the Spring and Autumn period in the state of Chu. It is derived from the Mi clan, where a noble named Xiong Jie had descendants who adopted the surname Jie. Later, a branch of Jie changed their surname to 蓝 after settling in Lantian (present-day Lantian County, Shaanxi). Additionally, another origin traces back to the Qin Dynasty, where descendants of the royal family were granted land in Lantian and took the surname 蓝.
