A mouse ran out from the dark orifice of the cave.

一只老鼠从黑暗的洞口跑出。

The hole yawned before him.

洞口在他面前豁。

The two floor openings were totally unfenced and the workers were not provided with any safety belt or fall arresting device.

两个洞口当时全无围栏阻隔，亦无给予工人安全吊带或防堕装置。

At the south of the hall, there is a vivid stalactite like a live lion at the ajar antre, so the hall was named “Lion hall”.

雄狮厅南端半敞洞口处的钟乳凝石酷似一头栩栩如生的雄狮得名。
