Please help me correct and improve this essay about travelling. It is for IELTS. Travelling is increasingly popular all over the world these days. Many people prefer to take a tour to other countries to learn different cultures there in their spare time. Generally speaking, the aboard experience will wide the vision of the traveler in certain areas. However, studies show that this is not always true for travelling people, many of which even narrow their mind after travelling aboard. How does this happen? This phenomenon, as far as I am concerned, is linked to their limited travel area and time. Most travelers prefer famous cities and natural stages when travelling aboard. Big cities likes London, Beijing, and New York are typically most developed areas in a country, which represent the modern culture and life. In contrast, the less developed cities or areas represents the traditional culture of a country. The travelers who denial to visit these less developed areas loss the opportunity to get a full view of a country. Another reason for the travelers to narrow their mind after travelling is that their travel schedule is too tight and their travel time is too limited. Many tour company make short and composite travel plans for the people who want to make a travel but do not have too much time. The travelers who take part in the tour company's travel plan are integrated into tour groups and are then directed by a tourist guide, who help them finish the travel in a short time. This kind of short travel, as far as I am concerned, just like the fast food, can provide nothing more than just an interesting experience. In order to form a full view of a foreign country, and thus wide their mind, the travelers have to make a detailed plan before their travel, which should provide enough time and space for them to learn the culture in a foreign. They should travel according to your own schedule rather than take the short travel plan provided by the tour company, which would otherwise narrow their mind.
