As a consumer, what I think of when I see this sentence is that the water of Nongfu Spring comes from nature, which is different from the artificially processed tap water, that is, the water from nature is put into bottles and sent to consumers. "We don't produce water, we are just porters of nature." On the one hand, it embodies the purity and clarity of aquatic products, on the other hand, it pretends to be a porter, which makes consumers trust and further proves that Nongfu Spring is sweet. This slogan is perfect.
