From 1903 to 1915, the Americans spent more than ten years building the Panama Canal. Since then, the Pacific and Atlantic Oceans have connected through the canal. The Americans held the "Pacific International Exposition to Celebrate the Opening of the Panama Canal" in 1915. This was the first and largest exposition in the world. 41 countries were invited to participate in the expo. At this expo, my country's "Baoning Vinegar" and "Moutai" each won a gold medal.
