The two main lines described in the film are very clear. One is Bogo's growing process from weak to strong. The second is the persistence of the hero and heroine in love. This humble love is deeply rooted in people's hearts and causes * * *. Haibo actually loves Bingbing deeply, but because of the special living environment, his way of treating love is different, but it also shows the truest performance of little people in treating their innermost desires.
In fact, Bing Bing is deeply in love with Lao Song. She gave all her great youth to Lao Song. Even if she met Haibo later, after the reappearance of Lao Song, the focus of Bingbing's life returned to Lao Song. The way they treat love is very hot, but the ending of their love is quite cold, just like the temperature under the ice, which will not freeze, but it is not warm enough.
