In fact, I really admire people who travel on foot. They use their feet to measure this world day by day. Among them, a man called Xu Xiake who was also a geographer who lived in the Ming dynasty, travelled through most of China on foot. He wrote down what he saw and heard which gave other people a chance to discover the outside world 500 years ago. He was great! His story always inspires me to overcome any hardships in my life. Trips have been playing an important role in our daily life. We have different purposes for travelling, either for fun or to challenge ourselves but both is OK! While planning a trip, a transportation is the first thing that comes into our mind. A plane, a train or a car is always prioritized. People might even take a rocket to travel in the future. But for people living in ancient times, their feet were the best transportation way for travelling. Though it's not ineffective, the belief in their mind helped them finishing their journey and even got some great achievements. So, can you make a decision on going on a trip on foot?
