Eason Chan's last line of " Ten Years "," Tears are not for you, but for others ", meant that even if people generally thought that the relationship was over, that person still left a mark in their hearts that was hard to forget. This sentence expressed the pain and struggle in the protagonist's heart because he not only lost that person, but also lost the meaning of this relationship. He had given a lot, but he still could not completely get rid of that person's influence. This sentence also hinted at the protagonist's emotional selflessness and generosity because he not only cried for that person but also for those who might never see him again. This kind of emotional expression is profound because it involves many aspects of people's lives, including love, friendship and loss.
