The Yantai hills account for 39.7% of the city's total area. The temperature difference between the ravine and the hills is large, suitable for the accumulation and full coloring of the cherry sugar. The warm temperate continental monsoon climate is extremely consistent with its growth cycle, and the country's unique North Sea climate is dry and not wet in summer. Winter is not dry, fruit trees are not suitable for mold and other diseases; sandy soil with deep soil, loose soil, good air permeability and strong water retention is most conducive to cherry growth.

Yantai is the northernmost green tea planting area in China. Affected by the warm temperate monsoon continental climate, the Yantai tea tree grows slowly, and the tea has a rich accumulation of nutrients and good quality. According to the tea quality supervision and inspection center of the Ministry of Agriculture, the green tea water extract produced by Yantai is 48.6%, which is 14% higher than that of southern tea. The amino acid, tea polyphenol, caffeine, chlorophyll and other important indicators reflecting the quality of green tea can be used with southern tea. Compared with the beauty, it has the characteristics of “the soup is green and bright, the leaves are thick, the aroma is strong, and the brewing is resistant”.
