Recently, Dong Mingzhu, chairman of Gree Electric Appliances, has once again become the focus of attention of **and**. Her company, Gree Electric, invested 1 billion yuan to enter the field of new energy vehicles. 
However, this decision does not seem to have been successful as expected, and instead has resulted in a huge debt of up to 20 billion yuan. There are profound lessons and thought-provoking questions behind this economic phenomenon. First, we need to understand the risks and uncertainties involved in investment decisions. 
Gree Electric invested in Zhuhai Yinlong, a new energy vehicle manufacturer, a highly competitive and risky industry with a constantly changing and uncertain market environment. While Gree Electric has been successful in the field of air conditioning and home appliances, venturing into new areas requires deep market insight and risk assessment, otherwise the consequences can be severe. The incident sparked a wide discussion about leadership responsibilities and the company's decision-making process. 
Dong Mingzhu has always been the leader of Gree Electric, and her decision-making and leadership style has great authority within the company. However, leaders must make decisions that take into account the long-term interests of the company, not just short-term goals. Decision-making should be a collaborative process that requires adequate discussion and deliberation to reduce risk. 
This incident is yet another reminder that companies must carefully consider the balance between risk and potential reward as they pursue expansion and diversification. Investment decisions require adequate risk management to ensure that the company's financial stability is not unnecessarily threatened. Gree's experience shows that excessive risk-taking can lead to irreversible consequences. 
Finally, let's ask a question that is related to today's article, but very different: what is the future of the new energy vehicle industry?Although Gree Electric has faced challenges in this field, the new energy vehicle industry is still considered to be the trend of the future. With the increase in environmental awareness and the support of ** policies, this field may usher in new opportunities and growth. We need to take a deep dive into the prospects for the new energy vehicle industry to understand its potential impact on the future economy and whether it will be the next growth engine. 
This question involves many fields such as economics, scientific and technological development, and environmental protection, which is of great significance for us to understand the future economic trend.
