Dear investors: How do you "show filial piety" to your parents?

My parents are both 65 this year, and according to rural sayings, if the day when the Grim Reaper doesn’t take them—73, 84—then in this world they can at most live another 20 years.

In the past few years, back in my hometown, I’ve attended my relatives’ funerals every year, and I’ve also realized that my parents are already growing old and near the end of their days! I’ve been thinking: how exactly can I repay them for their kindness and do my duty filial to them?

In these past few years, I’ve made a little money trading stocks. So I buy them things. I get them clothes, buy some daily necessities. Most of it is food. My father doesn’t smoke and doesn’t drink. So I buy him snacks. Of course, I’m a frugal-minded person; when I spend money, I’m particular about value for money. On JD.com I buy small bread, cookies, and milk powder. The imported milk powder on Pinduoduo—1 kg—only costs around 60 yuan. Each time I spend around 200-plus.
I’ve also thought about taking my parents traveling, but I’m a front-line worker who has to go to work, and my kids are in school so I don’t have time. Plus, my parents at home raise pigs, feed chickens, and work the land—there’s nowhere they can go.

To all you investors here, how do you “show filial piety” to your parents?
