Thanks so much for your comment! I'm glad to see that you are a regular use of WeChat. I also have started using the app, since so many of my family members do.
My aunts and uncles who live in China taught my grandma how to use the app. They installed it on her phone and tablet, and taught her the basic functions. My grandma's siblings also started learning how to use it around the same time, so they all learned together. She said that having a support group really accelerated the learning process. She also mentioned that she would be open to discussion advice on finances via this app, since all of her contacts are people in her life.
