So the sentence we have is: " A child next to an old man is a strong juxtaposition." So, the word " juxtaposition" , the word " juxta" actually means near and " position" means position, so near in position.

所有一话：“A child next to an old man is a strong juxtaposition” 。 所，“juxtaposition”这个词，“juxta” 这个词实际上指靠近， “position” 指位置，位置很近。
