Brazil's new President Lula was sworn in on January 1, and the largest country and economy in Latin America welcomed a new leader. In his inaugural speech, Lula stressed that the new government will be committed to "unity and reconstruction", solve various crises and challenges currently facing Brazil, and promote Brazil to return to the ranks of major economies in the world. In his inaugural speech, Lula called for national unity and social inclusion, and asked people with different political positions to put down their hatred. In fact, Lula has been focusing on the characteristics of "multi-party unity" since the beginning of her cabinet formation. The 37 ministers in the new cabinet come from 9 political parties, of which only 10 are elected by the Labor Party. Lula's practice of uniting multi-party parties to form a new cabinet is in line with the majority of the people who expect unity and reconciliation and oppose political polarization, reducing the obstacles that may be encountered in the process of governance. At the same time, the Brazilian economy is now showing a relatively stable recovery. The International Monetary Fund predicts that Brazil will rank the 12th largest economy in the world in 2022 and return to the top 10 in 2023. The implementation of national development plans such as reindustrialization, reducing the gap between rich and poor, solving hunger, improving the security environment, and enhancing the sustainability of social development have become the consensus of all sectors of the country, which is conducive to the Lula government's relevant policies and measures in these areas being widely recognized and supported by the society. In addition, Lula attaches great importance to foreign affairs. In the future, Brazil will highlight its influence in regional and emerging economies through mechanisms such as the Common Market of the South, the Community of Latin American and Caribbean States, and the BRICS countries, and use environmental resources of world significance such as the Amazon rainforest to reshape its global influence from climate, ecology, environmental protection and other fields. Brazil's international status is expected to be improved. Brazilian public opinion is full of confidence in the "unity and reconstruction" of the country. As Marcello, a political observer, said, if Lula and the new Brazilian government make good achievements in the opening year by virtue of their rich governance experience and political ability, then the current political situation will be comprehensively improved, and Latin America's largest economy will also usher in a better future. Analysts believe that Brazil's "unity and reconstruction" cannot be achieved overnight. In terms of "unity", Brazil has been affected by political polarization and split public opinion in recent years. Until the inauguration day of the new President, supporters of the previous President Bosonaro still tried to challenge the election results through various forms such as protests and demonstrations, while the largest party in both houses of the new Congress of Brazil is the Liberal Party where Bosonaro belongs. In the field of "reconstruction", Brazil's economic recovery is still climbing over the hill. Although inflation, unemployment and other livelihood issues have eased, they are still difficult to fundamentally solve. Hunger has affected the lives of low-income groups. Under the impact of internal and external factors such as repeated epidemics, sustained inflation, low consumption, and the Federal Reserve's continued tightening of monetary policy, Lula's plan to implement a series of new economic policies and social equality measures, such as reindustrialization and family subsidies, may encounter more interference. It will take a long time for the Brazilian people to realize their desire to improve employment and income. In recent years, due to the continuous interference of internal and external uncertainties in Brazil, Lula and his ruling team have a long way to go to realize the good vision of "unity and reconstruction". However, the Brazilian media pointed out that at present
