When I was doing foreign affairs reception work at the Beijing Hotel, some familiar foreigners told me that you oriental people tasted food, in other words, it was a grass taste. I didn't understand it, but I asked the Europeans, "Why are you all stinky armpits? That is, so-called fox odor." They peered at each other, and I wondered what it meant, and they couldn't smell any "stinky armpits" at all. When I came to Africa, the first few days, I was simply unbearable, the taste of African people, neither vegetable nor grass, nor the "smelling armpit smell" of Europeans, is completely a "soil" smell, that is a special "human taste", but, absolutely superior to "European taste", therefore, I couldn't smell it again a few days later. Later, I entered and exited Zambia seven times, not only did I not smell, but I had a sense of closeness. Why is this? After many inspections, I gradually realized that the truth is very simple, that is, "one side of the water and soil to raise one side of the people!"
