Firstly, for me it means help other people to gain knowledge in order to develop the society and make progress in the developing of it. secondly, helping other people to grow up and live not only to live, and also help others to make change in the society or in the country. Thirdly, the role of a teacher is to teach, but of course teaching is a long life process, so a teacher should always be open to learning because life always teaches new and different versions of different things. Last but not list, the development of each country is based on each individual of the country, and all the individuals are in hands of teachers.
