There are styles that previous preachers in our country used to read sermons in, and new preachers inherited them. We did not hear anyone in their time criticize their styles. However, these days, some people have mentioned that these styles are sung by some singers in some other countries. The question is: should the preacher pay attention to singing styles in the world so that his styles do not coincide with theirs, which is beyond human capacity, or is it enough to observe the style in his country and society?
