Yahoo is essentially an American Internet company. Like Google, it was unable to adapt to the local environment and withdrew from China. Originally, people who were acclimatized could be treated with traditional Chinese medicine. Zhou Hongyi was the master of traditional Chinese medicine who prescribed traditional Chinese medicine. However, Yahoo's guardian insisted on not using traditional Chinese medicine and insisted on using Yahoo's American constitution to support him. Zhou Hongyi, the master of traditional Chinese medicine, left in anger. In the end, Yahoo suffered from vomiting and diarrhea and was dying, and had to withdraw from China.
