I always avoid going on field investigations with the toxics (毒物)team, unless it's absolutely
necessary. It's not that I mind the hard work, or am afraid of coming into contact with toxic
substances. What I fear is quickly losing hope about the work I do.
However, doing field research with the toxics team, all I see and feel is filth-nothing else. Even
if I close my eyes, I can smell the smell of food processing, rotting organic waste from paper mills
and chemicals from clothing manufacturers.
One morning, I went to investigate a discharged pipe to document and collect samples of
pollutants secretly being emitted by a textile mill. I had to work with the utmost secrecy in order
to avoid being discovered by the textile mill.
I dipped a long measuring pole into the large polluting pipe to measure the volume of polluted
water being emitted. But the surface of the water, covered in oil and filth, made me feel as if to vomit.
All of a sudden, I felt someone hit me on my back. It frightened me so much that I almost fell
into the water. I grasped the pole and looked behind me to see an old man standing there. He
asked: "Can you catch fish here?" I realized that he thought I was holding a fishing pole, so I kept
calm and said: "Yes, I heard that there's a kind of small fish living in this water, and it has medicinal
benefits."
The old man grew quite curious and replied: "That may be. If a fish can survive in water as dirty
as this, it must have a lot of resistance. So it wouldn't be too strange if such fish had medicinal benefits."
It was clear he was just passing by, so I answered: "Yeah, survival of the fittest. Fish that adapt
can survive, just like us humans."
He kept talking to me and didn't want to leave. He wanted to see whether or not I would catch
the small fish with medicinal benefits.
