There is a Catholic community in Hsinchuang/Taishan run by the Sisters of Providence that does a lot of work feeding people, caring for housebound people, and so forth. I do pro bono translations for them when possible, and I’d strongly recommend them as a good place if you want to donate money and have it get to the people you want to help as opposed to being sucked up by administration and so on.
The place is called “Miracle House” (“qi ji zhi jia” in Chinese). You can get there on a bus from Hsimen MRT if you feel like volunteering. They have an American sister there at present who is a very cool lady as well, and Sr. Ma speaks good English as well.
