Before it became a Communist Party retreat, Beidaihe was an international playground. During the Guangxu reign of the Qing dynasty, foreigners living in Beijing petitioned for permission to build summer villas along this coast, and in 1898, the Qing government officially designated Beidaihe as a 'summer resort for people of all nations.' By 1949, 719 villas dotted the hillsides and shoreline -- Russian musicians played outdoors near their cottages, European diplomats escaped the capital's summer heat, and the pine-covered slopes of Mount Lianfeng provided shaded walks above the beach. The shallow water, the fine sand stretching a hundred meters to the sea, and the lush vegetation of caves, pavilions, and winding bridges made Beidaihe irresistible to anyone who could afford the train ride from Beijing.

After Mao Zedong led the Chinese Communist Party to power in 1949, the new leadership inherited a taste for Beidaihe's seaside atmosphere. Mao himself maintained a summer residence here. Sanatoriums sprang up to reward model workers from every industry -- the resort became simultaneously a political nerve center and a vacation destination for the ideologically worthy. In 1954, a large Friendship Guesthouse was built to host Soviet advisors, the 'elder brothers' assisting Chinese development before Sino-Soviet tensions fractured the relationship. That same year, Mao composed one of his most celebrated poems while at Beidaihe. But the resort's most dramatic moment came on September 13, 1971, when Lin Biao -- accused of plotting a coup d'etat against Mao -- fled to his Beidaihe villa with his wife and son, then boarded a plane bound for the Soviet Union at the local airport. The aircraft crashed in Mongolia, killing everyone aboard.

For decades, the Chinese Communist Party's highest leadership gathered at Beidaihe each July, slipping away from the summer heat of Beijing to plan strategies in the resort's discreet setting. These informal conferences had no official agenda and no published minutes, but their outcomes shaped Chinese policy. In 2003, Hu Jintao abandoned the tradition, citing two reasons: holding conferences at a resort contradicted his goal of projecting a frugal image for the party, and he preferred to work through formal party mechanisms rather than informal seaside gatherings. The hiatus lasted through Hu's entire tenure. When Xi Jinping came to power in 2012, the Beidaihe summer retreat quietly resumed -- officially unacknowledged, as always, yet widely observed. The pattern -- official cancellation followed by informal resumption -- captured the essential nature of Beidaihe itself: a place where the machinery of Chinese politics operates just out of public view.

Beidaihe's political significance can overshadow what drew people here in the first place. The district covers just over 70 square kilometers with 22.5 kilometers of coastline and a population of roughly 130,000. Beyond the beaches, it is known as a birding haven, sitting along a major East Asian flyway where migratory species pause on journeys between Siberian breeding grounds and Southeast Asian wintering sites. Mount Lianfeng, with its twin peaks covered in pines and cypresses, remains the kind of place where you can lose yourself on winding paths between decorated pavilions and small caves, hearing nothing but wind in the trees and the distant sound of waves. The beach itself -- shallow, warm in summer, sheltered from the worst of the Bohai winds -- still draws visitors from across China who come for the same simple pleasure that Russian musicians sought in 1905: an afternoon by the sea, away from the heat and complexity of the capital.
