Tai Sheung Tok used to be 419m (1,375ft) in height, but because of mining activities by K. Wah Group (owned by Lui Che-woo who went on to become Macau gambling mogul) at the Anderson Quarry in the 20th century, its height has been reduced to 399m (1,309ft).[1]
Civic construction work on the Development at Anderson Road (DAR)[2] is being finished, while another project called the Development of Anderson Road Quarry Site (ARQ)[3][4] has recently commenced at the foot of Tai Sheung Tok.
