There are really a lot of ways to do Charity, some doesn't require money to be able to do it. As long as you do the deeds with a happy heart, then that'll be enough. I love those you mention here. Simple things is what makes everything more special and by doing those we can really bring a lot of joy to everyone. As for me I can only do cash, if I have it, or if not, then a Prayer. Or even by jusy sharing the Charity work you know to one community, that is also a big help already (人 •͈ᴗ•͈)
