What kind of gifts do you prepare for your mom and dad on New Year's Day?

Home for the New Year, I'm going to give my dad a pair of good quality knee pads, because he was young and working outdoors in northern Shaanxi Province, the conditions are very difficult, the weather is cold and there is no good warmth measures, the knee suffers from the cold, every winter will be hidden pain, I hope that soft knee pads can protect my dad's legs, to alleviate the pain of his old man. I am going to bring a few books to my mom, she was an elementary school language teacher when she was young and loved the works of masters such as Lao She, Zhu Ziqing, Zhu Guangqian, etc. Now that she is retired and lonely, it is a good idea to feed her. Now retired is very lonely, raising flowers and plants, dancing, sometimes with presbyopia sitting on the balcony to read books, I hope that mom will be happier when she reads her favorite books.
