The graph illustrates the number of inquiries received by the tourist information office in three forms ( In-person, By letter/email, and By telephone) in one city over six months, produced from 2011.
It is clear that in-person enquiries are more than the other two inquiries, by letter/ email, and by telephone from January to June with 2000 people.
In January 2011, 400 people were investigated in in-person, which was rapidly increased by 1900 investigators in June, followed by letter/email. 900 people queried by telephone in January considerably raised by 1600 in June. 800 enquirers, enquired by letter /email in Jan, which was gradually decreased in the month of June by 300 in the tourist information office in six months.
It shows that people go directly to the office to gather information more than the other two sources, and few people only get information by sending a letter or email for their inquiries.
