Internet reports that at the college graduation ceremony, US President Trump advised business students to join factories and workshops to "move bricks and stop thinking about financial speculation every day." He told business students, Don't just use your talents for financial speculation, but use the excellent skills you have learned and mastered to devote yourself to new factories, workshops, shipyards, and even emerging cities in the United States. In the construction of cities, make real efforts like forging steel and pouring concrete, not just to create a strong investment portfolio. (Observer Network)
