My father is engineer. Although he is in Africa most time of the year and there isn't much time for him to reunite with the family, but we are all proud in him. He builds railways there. It is an importance part of the great Belt and Road Project. At first people there found the Chinese and their work strangely. My father often saw people running after trains out of curious. People there even didn't understand that the Chinese people work very hard. Gradually, however, the African people come to see the benefits bringing by the railways and they are now willing to make friends with the Chinese here. My father has already made some African friends and one of them is planning to come to visit us. We are looking forward to show our African guest around our city.
