The Story of An Old Rusty Metal Box

Many years ago, I'd heard from an elderly work colleague who told me about a construction worker driving a bulldozer, demolishing an old concrete house, somewhere in the Chinatown area.. 

On one fine day, this worker had dug up an old rusty metal box containing cash and gold jewelry. This worker couldn't even be bothered to collect his salary, and he'd disappeared right away without any trace. 

Nobody had ever heard from him anymore since that time.
