我们应当给帮带孩子的父母工资吗？Should we pay our parents for their babysitting?

It seems so normal that parents will take care of their children’s children in China. We can see a large crowd of grandparents standing in front of kindergarten to pick up their grandchildren. It seems that taking care of grandchildren has become grandparents’ obligation. They should do it for free. However, now this concept has changed, some people said that parents should get the payment for their babysitting, because they are old and babysitting is a heavy work; while others think that parents should do it for free. In my point of view, I agree with the former one.
在中国，父母帮自己的孩子带小孩是非常正常的，我们能在幼儿园看到一群在门口站着等着接孙子的祖父祖母。看起来带孙子已经成为祖父母的义务了，他们就应当免费干这事儿。然而，现在这种观念变了，有些人认为父母带孩子应当给工钱了，因为他们老了，带孩子是项累人的活儿；然而有些人认为他们就该免费这么做。就我看开，我同意前一个看法。
In the first place, parents’ duty and obligation is to raising their children until they have reached an adult age, but not still raising their children’s children. There is no doubt that raising a kid to adult is a difficult thing. It requires a lot of love and money. In China, most parents give the child university tuition and living expenses. They want their kid could focus on learning. Some parents even spend money for their child to find a good job which is secure. Our parents had already done so many things for us without any return. It would be a shame to ask parents to look after our children for free in their age.
第一，父母的责任与义务就是把他们的孩子养到成年，而不是继续养他们孩子的孩子。毫无疑问的，养大孩子是件难事，这需要大量的关爱与金钱。在中国，许多父母为孩子付大学费用和生活费，他们想让他们的孩子专心学习。有些父母甚至会为孩子的铁饭碗工作而花大钱。父母已经不求回报地为我们做了这么多事情。如果再叫年老的父母免费给自己带孩子，那实在是太羞愧了。
In the second place, someone argue that the days are tougher than before, we should not give extra pressure to young couples. It is true that the competition is fierce than before, but think about it, parents must had been through a more difficult period to raising a child in the old age, for every conditions of life are in a low level. They give their best for their children, and when they are old, they still do the same thing for their grandchild. I think it is reasonable to pay them back.
第二，有些人认为现在的日子比以前难过，我们不应该给年轻夫妇增加额外的负担。现在的竞争比以前激烈是不争的事实，但是想想看，父母以前养孩子肯定也经历过一段很艰难的时期，因为以前的各种生活条件都比现在低。他们给孩子最好的了，他们老之后，也是把最好的给孙子。我认为补偿他们一下是非常合理的。
To sum up, parents deserve better in later life, even most parents are volunteer to do babysitting, young people should show some responds, they could pay them back with money, if it will increase the economic burden, then they could share the babysitting with them and love them more.
总而言之，父母应该过个更好的晚年生活，尽管大部分父母是自愿带孩子的，年轻人应该做点反应，他们可以给点钱他们，如果这会增加经济负担，那么他们分担点带孩子的事还有更爱他们的父母也是可以的。
