What should be the warmest place is actually the most uncomfortable place

The following is the answer to a classical Chinese novel: The story began in a quiet and beautiful village. The protagonist was a young wife who spent many happy times with her husband in this place. However, fate was unfair to her. Her husband suddenly contracted a rare disease. The doctor told them that they could only live for the last semester. At this critical moment, the protagonist decided to leave this place to find more opportunities for treatment. She and her husband took a train through hundreds of miles of wilderness and mountains and finally arrived at a strange city. Here, the protagonist found a well-known doctor who told them that her husband's illness could be cured, but he needed a special herb that could only be found in a very remote mountainous area. The protagonist began a long search through dense forests and steep valleys until she finally found the herb plantation. However, when she got there, she found that the plantation was too far from the city to reach. She had no choice but to give up on finding this herb and return to her husband's side. Although she wanted to continue searching for the herb, she knew that this was her only chance, or her husband would die. Back in the village, the protagonist found that she no longer felt as warm and comfortable as before. She found that her husband had died and her children had left the place. She began to live alone, but she knew that her husband had spent a lot of good times here, and she didn't want to lose this beautiful memory. Although this place used to be her warmest place, it was now the most uncomfortable place for her. She missed her children and her husband, but she also knew that she had to live strong. She began to replant her husband's inheritance and rebuild the village, hoping to make the place better.
