Ideals and beliefs are not only a matter of ideological understanding, but also a matter of practice. This sentence is correct. Because ideals and beliefs are not dreams or slogans that stay at the ideological level, but need to be implemented in practical actions to achieve their goals and pursuits through practice. Only by transforming ideals and beliefs into concrete actions and practices can we truly realize ideals and life values. Therefore, we need to strengthen our ideals and beliefs, keep working hard and work hard to achieve our goals in life.
