生命的意义何在，存在有什么理由？这样有什么意义可言吗？作为一只狗，可选择的生活方式会有什么呢？我们还是从故事的开头说起吧。
What is the meaning of life and the reason for its existence? What's the point of this? As a dog, what is the alternative lifestyle? Let's start with the beginning of the story.
贝利的第一世过得很幸福，有主人的陪伴和呵护，所以它很依赖它，但是，随着主人的离开，贝利就开始孤独起来了，它无时无刻都在思念着自己的主人，以至于到最后它都没搞明白，为什么人类那么复杂，为什么总是做狗不明白的事，例如：离开。其实，这也真实的演绎了人类的孤独生活，为什么会分离和孤独呢？
Bailey's first life was very happy, accompanied and cared by his master, so he relied on him very much. However, with his master's departure, Bailey began to be lonely. He was missing his master all the time, so that he didn't understand why human beings are so complicated and why dogs always do things they don't understand, such as leaving. In fact, this is also a true interpretation of the lonely life of human beings. Why is it separated and lonely?
贝利经历了四生四世，最另我敬佩的是做警犬那一世，虽然镜头不多，但是感动到落泪。贝利这次变成了警犬，贝利很聪明，干过不少好事，在办一起绑架事件时，被绑架的女孩不小心掉河里了，贝利也跳下去救人，将人送上岸后，再上去帮警官，但在警官没注意时，歹徒想从后边射死警官，就在这时贝利将他推到，可惜歹徒射死了贝利。这一世可以说是它光荣的完成了自己的使命。
Bailey has experienced four lives and four lives. What I admire most is being a police dog. Although there are not many scenes, Bailey is moved to tears. Bailey became a police dog this time. Bailey was very smart and did a lot of good things. During a kidnapping, the girl who was kidnapped accidentally fell into the river. Bailey also jumped down to save people and sent them ashore to help the police officer. But when the police officer didn't pay attention, the gangster wanted to shoot the police officer from behind. At this time, Bailey pushed him to the police station, but the gangster shot Bailey. This life can be said to be the glorious completion of its mission.
最后贝利获幸，又看到了第一世的主人，但主人却不认识它了，贝利用它的接飞盘绝活让主人认出了这是小时候的贝利，最后他们还是永远的在一起。
Finally, Bailey was lucky to see the master of the first life, but the master didn't know him. Bailey used his flying saucer skills to let the master recognize Bailey as a child. Finally, they were together forever.
影片看似在说狗生，其实倒不如说是讲人生。孤独始终是常态，但是我们每个人都有每个人的使命，不管生活如何，我们要活在当下。
The film seems to be talking about dog life, but in fact, it's more about life. Loneliness is always the norm, but each of us has a mission. No matter how we live, we should live in the present.
世界那么大，很庆幸遇到你，若我能将幸福带给你，我将完成了我的使命！
The world is so big, I'm glad to meet you. If I can bring happiness to you, I will complete my mission!
