要知道美國與墨西哥同屬北美洲國家，而且與美國還是鄰國，這就導致大量墨西哥公民會偷渡至美國境內。因此經常在兩國邊境線上可以看到很多偷渡者，然而美國前總統特朗普為了阻止這種情況的發生，曾經斥巨資修建墨西哥墻，可是最終因為經濟實力不足，中途便停止修建。（It is important to know that the United States and Mexico are both North American countries and are also neighboring countries with the United States. This has led to a large number of Mexican citizens smuggling into the United States. Therefore, many illegal immigrants can often be seen on the border between the two countries. However, in order to prevent this from happening, former US President Trump has spent huge sums of money to build the Mexican Wall, but in the end, due to insufficient economic strength, the construction was stopped midway.）
