Personally, I suggest going to Huafeng Commercial Street at the north end of Linxi Road 1 Water Bridge, where ice cream powder is not only sold, but also cheap.
Linyi, formerly known as Langya and Yizhou, is a prefecture-level city under the jurisdiction of Shandong Province, a second-class big city, a central city in southeastern Shandong, a modern industrial and trade city with waterfront characteristics, a trade and logistics center approved by the State Council, and an important commodity grain base in Shandong Province.
