Why does Lesotho's tourism develop well?

The highest country in the world is Lesotho, a small country in southern Africa with beautiful mountains and rivers and unique scenery. Every inch of land in China is above 1000 meters above sea level, and it is known as the "kingdom in the air". Lesotho's picturesque scenery, pleasant climate, magnificent waterfalls, deep streams, majestic peaks and castles, pleasing lilacs, exotic straw hats and gorgeous carpets used by local people ... all these make Lesotho a tourist attraction with unique taste and the national cultural quality has generally improved, so Lesotho's tourism industry has developed rapidly, accounting for about 12% of its fiscal revenue.
