The Antiquities and Monuments Office (AMO) received a citizen's report on 7 May 2004 that relics were found at a works site at the junction of Soy Street and Tung Choi Street in Mongkok.
With the assistance rendered by the consultant and contractors of the Drainage Services Department (DSD), staff of the AMO reconstructed how the relics were found in the trench and investigated the soil and layers that might bear relics. The original landscape of the site had been changed drastically and frequent disturbances caused by recent urban development were shown. The trench was full of pipes and piles. The relics might be deposited in a brownish sandy layer between the modern disturbed layer and the greyish sand of marine deposit. Four flat-bottomed pottery pots were found on that day.
On 10 May 2004, staff of the AMO monitored the works and noticed other relics in the trench. At the request of the AMO, the DSD and its contractor immediately suspended the works and provided assistance in clearing the soil. Over 100 pieces were collected in this operation, including a broken pot, fragments of a pottery cauldron, kiln debris and associated furniture as well as various village ware sherds and grey bricks. Since there was no further discovery, the site was then returned to the DSD the following day.
The important relics collected from this site include pottery pots, fragments of pottery cauldron, kiln debris and associated furniture. There are five pottery pots, of which four are complete and attributable to the Han dynasty (206 BC – 220 AD). The completeness of pottery pots implies they might have been burial objects. The kiln debris and furniture might be the remains of the Tang dynasty (618 – 907 AD).
