Speaking of the food customs of the Dragon Boat Festival, it is natural that Zongzi cannot be omitted, which has a history of thousands of years. Shandong people love to wrap zongzi with glutinous rice or yellow rice, and there are many fillings, but the most traditional one is yellow sticky rice with dates, which are wrapped in reed leaves into triangles, commonly known as "jujube zongzi". In Yimeng mountain area and Rizhao area of Linyi, a kind of Bole leaves wrapped zongzi is commonly used on the hillside.

In addition to zongzi, a special food for the Dragon Boat Festival, there is also the custom of eating mugwort leaves and boiling eggs during the Dragon Boat Festival in all parts of Shandong. In the early morning of the Dragon Boat Festival, the family put fresh wormwood in the pot to boil eggs. When the egg is cooked, the skin of the egg turns slightly green, with a slight smell of wormwood.

Bitong drinking is a custom in Jinan. Picking fresh lotus leaves that have just emerged from the water to hold wine, piercing the heart of the leaves to make them communicate with the stems, and then sucking wine from the stems, people drink lotus stems, and the wine flows into the mouth, becoming a summer drink during the Dragon Boat Festival and even in hot summer.

According to historical records, in ancient times, when the lotus flowers in Daming Lake were in full bloom, some officials and scholars often went to the lake for the summer. They cut off the lotus leaves in the lake, filled them with wine, and stabbed the central part of the lotus leaves with a hairpin to make them communicate with the hollow lotus stems. Drinking wine from the end of the lotus stem, "the wine tastes mixed with lotus fragrance, and the fragrance is colder than water."
