What do you mean, don't hold the country back?

If we do not delay the country, we will not delay the efficiency of the country. If we don't put the country in trouble or delay, we should take the initiative to solve our own problems and pursue a higher level of material and spiritual life. A drag is that there is always one person who is the worst and cannot keep up with the overall level. A metaphor for hesitating, hindering others or things from making progress.
