请帮忙把这段翻译成中文。

In the wilderness on the outskirts of Yong Zhou there exists a kind of snake with black skin marked with white stripes. Any plant dies upon its touch and anyone bitten by it is doomed to die. But once it is caught and dehydrated, it can serve as an ingredient of a traditional medicine for the cure of leprosy, arthritis, swollen necks, malignant tumors, the removal of decayed flesh, and the elimination of three kinds of worms that cause illness. Since early times the court physician has ordered the people in the name of the emperor to hand in snakes twice a year. Whoever does so is exempted from taxation. People are vying with one another to catch snakes.

There is a man whose surname is Jiang. His family has been enjoying this privilege for three generations. When asked, he told me with deep grief, My grandfather was killed by a snake, and so was my father. I myself have been engaged as a snake catcher for twelve years and might have been killed many a time. I sympathized with him, saying, Are you complaining about this work? I shall ask the official in charge to transfer you to your former work and renew the taxation on you. How would you like that?

My words threw him into great agony. He burst into tears and said, Do you pity me and want me to live on? But the misery I am suffering now is not at all worse than what I suffered before. If I had not taken this work, I would be in desperate straits. Three generations of my family have been living here for sixty years. Our neighbors are growing poorer day by day. In order to pay the taxes, they are compelled to hand over all the produce of their land and all the possessions in their house. They shuffle from village to village, wailing in distress, and many of them die of hunger along the way. They are beaten by wind and rain, suffering freezing cold in winter and scorching heat in summer. What\'s more, they have to inhale the pernicious air of deceased districts. In this way, people are dying one after another, and their dead bodies are piling up. Out of ten families that were my grandfather\'s neighbors, only one has survived, and out of ten families that were my father\'s neighbors, only two or three remain. As to the neighbors who have been living near me for the past twelve years, only four or five out of ten families have survived. Most of them are dead or have moved to other places. I luckily remain alive simply because I am a snake catcher. Whenever the relentless officers come to the village, they make a row and bully the people. The village people scream from terror. Even fowls and dogs are not left in peace. I get out of bed with fear and look into the jar. To my relief the snakes are still there. Then my mind is at ease and I return to bed. I feed the snakes with great care and deliver them to the authorities in time. Back at home, I eat the produce of the land so that I may live on till my death. I risk my life only twice a year. The rest of the time, I spend my days quite happily, unlike other village people whose lives are constantly threatened. Even if I were killed by a snake today, I would still have lived longer than my neighbors. Why should I complain?

I feel all the more depressed upon hearing his story. I was once disbelieving of Confucius\'s words: Tyrannical rule is more ferocious than a tiger. From Jiang\'s example I have come to realize that this saying is true. Alas! Who could have known that oppressive taxation is worse than venomous snakes? Hence I write down this story for those who are making investigations relating to the life of the common people.
