I've got two questions. First, which dayi should I buy? I probably don't need both, but I don't know if I should get the younger or older one (or a different year entirely).
Second, which sanhe liubao? I don't need both, but I don't know what the difference is gonna be between the 0222 brick and the chen nian bing cake.

Also tell me if I'm being retarded on anything else
