Grandpa Shen, the panda, will send good bamboo if he wants. There are many bamboo forests in spring and summer, and sometimes Mallow (the little girl in Huacun Hotel) will be given this task. Yaxiu, an animal shop, can send hot milk as long as you can raise cattle. You can make a milk+pot every day (it's in the menu, take your time).

I suggest you search online again, or go to the story of the ranch, where there is more information. I hope I can help you!
