In Dongying, the Yellow River found its final destination, flowing east to meet the sea. It is said that Dongying is half the sea, half the oasis. What effects will the embrace of the Yellow River and the sea have? Let's follow the footsteps of Qingyi, a Russian student at Shandong Jiaotong University, to find out.

It is the eastern wetland city, the central city of the Yellow River Delta, the second largest oil field production base in China, and the birthplace of Lv Opera and the hometown of Sun Wu. It has the most complete, broadest and richest wetland ecosystem in China. This is the youngest land in China, Dongying.

Zhao Yajie, who works at the Yellow River Delta Environmental Monitoring Center, often takes a telescope to check the habitat of migratory birds in the Yellow River Delta National Nature Reserve. According to her, more than 6 million birds come here every winter to roost and breed, so the reputation of "Dongying·Birds International Airport" was born.

Smart birds flock together to stay above the waves at the confluence so they can feast on delicious"river fresh" and "seafood." Speaking of "river fresh,"  the first thing that comes to mind is the plump crab roe of the Yellow River estuary crab. It's irresistible just thinking about it.

Han Hao, marketing manager of Dongying Huize Agricultural Technology Co., Ltd., and his team have been busy before the crab harvest. Many customers are rushing to order the delicious food on the table before the Mid-Autumn Festival.

As entering the golden autumn, Yellow River estuary hairy crabs will become plump. This is due to the rich nutrients brought by the confluence of the Yellow River estuary, and the hairy crabs in the Yellow River estuary are particularly plumper. The crabs here are known for green shells, white bellies, and plump crab roe.

In addition to the delicious Yellow River crab, Dongying is said to have the world's largest "two-flavor hot pot." When the Yellow River flows into the sea, it creates a world wonder that is “half mixed yellow and half sea blue.”

This is the end of the Yellow River, from the Bayan Har Mountain in the Qinghai-Tibet Plateau to the Yellow River Delta in Dongying. When the Yellow River and blue sea water embrace each other, they create a "river and sea intersection" wonder that attracts countless tourists.

The huge transformation from "oil city" to "green city" could not have been achieved without the efforts of generations of oilfield workers to "develop while protecting, and protect while developing." The oil production area where Han Jiguang, a staff member of Gudao Production Plant at Shengli Oilfield, is the most remote and scattered management area of Shengli Oilfield in Shandong Province. The entire oil field is located in the Yellow River Protection Zone, but there are some scattered plots outside the scope. Therefore, environmental protection, flood prevention and ice prevention are also an important work.

They have seen the island turn into a home.

They have seen the wasteland turn into fertile fields.

Stretching 138 kilometers, the Yellow River corridor guards the Mother River like a long green dragon. The Yellow River, which gave birth to the splendid Chinese civilization, ended its 5,464 km journey here and then merged into the sea.
