Lei Cheng Uk (Chinese: 李鄭屋) was a group for villages of families of Lei/Lee/Li (李) and Cheng (鄭). The villages were demolished for building a public housing estate, Lei Cheng Uk Estate. At the beginning of the construction, a Han tomb was found there and named as "Lei Cheng Uk Han Tomb", which later became part of the Lei Cheng Uk Han Tomb Museum.
