The literal translation of the title of this movie is: for the 61 brothers (of the working class).
Although the movie was based on the real event and it gives a rather accurate depiction, but it is not without flaws. One of the most obvious flaw is that the plot appeared to work backward, based on the actual results in the real life. For example, the medical and rescue crew appeared to be successful in solving every problems in a way that they already knew the answer, because every step they took produce the correct results. In reality, the situation was much more desperate because they did not know what to expected, and this point was not accurately enough in the movie.
