Liu Ying still didn't know what had caused her to be infected with Tetanus. Was it the old fish hook that she bought for twenty cents from a small shop, or was it the dirty soil that got on the fish hook when the carp was struggling on the ground? In short, it was the most serious illness she had ever had since she was a child. Fortunately, she did not have any sequelae and grew up healthy.
In fact, to a certain extent, she was quite grateful to the little fish hook. If it wasn't for the sickness, her Grandma would not have cared for her, and she would have been too afraid to spend every afternoon alone with only the fish tank, carp, and loach as a company.
As a small coastal fishing village, fish were both food and commodity for the villagers—big fish were food for the people, while small fish and shrimps were food for the chickens and ducks. Not many people treated fish as pets, of course, and they also did not normally cure fish of their sicknesses.
