Read the answer, the pain and joy of sericulture

The pain and joy of raising silkworms Our Hai 'an is a well-known hometown of cocoons and silk in the country. There are many families that raise silkworms. We visited a few families and learned about the situation of silkworms. The feeling we got was that although silkworms are bitter, there is joy in the bitterness. Old Man Li's family raised three pieces of paper silkworms. He said that raising silkworms was a bit hard. Silkworms were very delicate and had to be taken care of day and night like taking care of babies. Every time there was a silkworm, he had to get up a few times at night to go to the silkworm room to take care of it. During the month of rearing silkworms, it was relatively busy, especially during the time when the silkworms slept four times and went up the mountain to make cocoons. They had to work at full capacity for seventeen to eighteen hours every day. After talking about the hard work of raising silkworms, Old Man Li changed the topic. When I was young, my neighbors raised silkworms. There were no mulberry fields (climbing mulberry trees to pick mulberry leaves), no technical guidance, no medicine for silkworms, and the price of cocoons was not as high as it is now. It's different now. The National Silkworm Egg Farm provides high-quality silkworm eggs, there's a specialized silkworm medicine sales department to supply silkworm medicine, the government has specialized technical personnel to help farmers raise silkworms through radio speeches and on-site guidance, and the purchase of cocoons is open to the government at a protected price... The common people have a strong guarantee for raising silkworms." It happened to be National Day, and the four cocoon stations in the town began to weigh and collect cocoons. We arrived at Dengzhuang North Station. Here, we saw long lines in front of all the cocoon-selling windows. Bags of cocoons could be seen everywhere, and the silkworm farmers were all smiling. We walked around the cocoon station, heard and saw the villagers talking about their harvest, comparing the quality of cocoons and the amount of income. We deeply felt that the farmers 'lives were getting better day by day! 1 Take a metaphor. 2. Which natural paragraph wrote about the bitterness of silkworm rearing?
