Well, overall, this movie is not bad after all..
But if you are not a family kind of person, then i suggested don't watch this movie better because although it is about disaster movie but the main focus is still about family..
The flow might a bit fast because it told a story about a family for 32 years. Hence, it didn't have much details on every single scene..
As for the story, basically it told an incident that struck TangShan, China, an earthquake that devoured 240k or more of human lives..

Overview of the story:
A 7-year-old girl who get buried under the debris after the earthquake, overheard her mother decision to save her twin brother, who get buried under the same debris, instead of her because her mum have to come to difficult decision to choose to save either one of them or to lose both of them..
1 second more hesitation, they both will get crush to death by the debris. It is the most painful decision the mother had made in her life. As for the 7-year-old girl that overhead the conversation, can only quietly cry and say "ma..ma.."

As her mother thought her daughter was dead, she rush her son to the hospital leaving the girl body among the dead people..Miraculously, the girl woke up, but she had no intention at all to look for her mum..She walk aimlessly among the dead body till someone approach her asking," where is your family, your dad, your mum?"
The girl can only give an innocent sad face while looking at the guy, "don't be afraid, uncle will bring you home" responded the guy..

Well, so the rest is about family scene, about how the girl face her childhood traumatised experience..
To be honest, i don't really like the character of the small girl when she grow up..so insensible, only know how to make parents worried..in a word, to me i think she is selfish..I like the character of her mother, although stubborn but she is devoted, No doubt about her love for her husband and her child..
