At 5 am, Wang Piyu, deputy director of the Changhai County Natural Resources Affairs Service Center, sets out by patrol boat for Fantuozi Island, a core breeding site for Chinese egrets in the Changshan Archipelago, Northeast China's Liaoning Province. The island has no permanent residents.
About 100 meters from the island, Wang turns off the engine and reminds accompanying researchers to keep their voices low to avoid disturbing the nesting birds.
Stepping onto the island, they walk along paths covered with vines. Scattered across the rocky slopes are nests measuring 40 to 50 centimeters in diameter. Inside, fluffy chicks huddle together among soft grass woven into nests, while adult birds perch high in the trees, watching cautiously.
"This was not what the island looked like 10 years ago," Wang recalled. "People used to collect eggs here, and coastal aquaculture polluted the tidal flats. Many parts of the island were bare, leaving little vegetation for birds to nest."
The recovery of Changshan Archipelago, however, has turned the remote archipelago into an important link in global conservation efforts.
At the 48th session of the UNESCO World Heritage Committee in Busan, South Korea, the boundary modification of the Migratory Bird Sanctuaries along the Coast of Yellow Sea-Bohai Gulf of China was approved, officially adding the Changshan Archipelago to the World Heritage site.
The expansion further strengthens the integrity of the serial natural heritage site, following a previous update in 2024, and highlights China's efforts to integrate coastal ecosystem conservation, according to the National Forestry and Grassland Administration.
Behind the World Heritage recognition lies years of conservation work involving local authorities and island residents.

Located in the northern Yellow Sea off Dalian, the Changshan Archipelago sits along a key route of the East Asian-Australasian Flyway, providing an essential stopover where tens of millions of migratory birds replenish their energy during their journeys across the Bohai Sea.
The newly added area covers more than 4,900 hectares and is home to more than 140 recorded bird species, including the Chinese egret and black-faced spoonbill, both listed as China's national first-class protected animals.
In 2015, more than 300 Chinese egrets arrived in Changhai county. After discovering the birds, local authorities introduced a series of protective measures, including establishing patrol teams and installing remote monitoring systems to reduce human disturbance.
However, the growing bird population also created new challenges.
Less than half of Fantuozi Island was covered by shrubs, which serve as the nesting grounds for the egrets. Additionally, the island's poor soil and acidification caused by years of accumulated bird droppings had led to the withering and death of some shrubs in recent years.
From 2022, the county launched an ecological restoration project, replacing surface soil with fertile earth and planting more than 2,200 shrubs.
The efforts helped restore the breeding habitat. The number of Chinese egrets on the island has since recovered, with this year's population estimated at about 3,500, including around 1,500 adults and nearly 2,000 chicks, according to Lü Yongquan, director of Changhai county's natural resources bureau.
"Chinese egrets are highly sensitive to water quality, vegetation and human disturbance. Their return to breed here is a sign that the marine ecosystem has recovered and is thriving," Lü told the Global Times.
From fishermen to guardians
Conservation in Changhai is not only carried out by authorities. Local communities have also gradually become part of the protection network.
Authorities have expanded public awareness campaigns and strengthened patrols. Because most of the Changshan Archipelago is uninhabited, drones, fixed-point infrared cameras, and on-site inspections are used to monitor the islands and reefs around the clock.
Many fishermen who once relied on the sea for their livelihoods now help protect it.
During the peak breeding season from April to July, regular marine patrols are carried out to protect nesting sites and prevent illegal egg collection and habitat damage. Local bird conservation groups and research institutions have also joined the efforts, while fishermen have taken on new roles as volunteer guardians of the islands.
Across Changhai county, many fishermen now actively participate in coastal patrols to help protect the archipelago's biodiversity.
For Li Qingsen, a 50-year-old island native and member of the county's forest fire brigade, protecting the birds has become a way of life.
From spring to autumn, 20 team members take turns staying on Fantuozi Island in pairs to protect the birds from disturbance.
Life on the 0.08-square-kilometer island is far from easy. There are no freshwater sources or docks. Patrol workers carry large barrels of water and wade ashore from boats anchored offshore. Instant noodles are often their main food because they require little preparation and some water.
Their work is closely tied to the seasonal cycle of the birds. Each April, thousands of Chinese egrets arrive in the archipelago from Southeast Asia to breed and rear their young, staying until early September before migrating south for the winter.
At present, young egrets are already practicing flight above the treetops. By autumn, they will join their parents in a southward migration.
For Wang, who has spent half of his life guarding Fantuozi Island, the World Heritage recognition is both a homecoming for the birds and a reward for years of protection. "Now, it is a home for the birds, and a reward for all the years we have spent protecting it."

在美国斯坦福大学举行的半导体学术会议Hot Chips 2026上，三星相关负责人首度公开展示了LPDDR5X-PIM的结构、规格及验证结果——该产品本月初刚在FMS 2026内存会议上斩获下一代内存奖项，但详细参数直到此次会议才正式披露。

二 | PIM（内存内运算）技术通过在内存中嵌入运算单元，使部分计算可直接在内存内部完成，无需像传统架构那样将数据频繁搬运至CPU或GPU再传回内存。 对于AI运行而言，数据搬运是主要性能瓶颈之一，应用PIM后，简单运算就近处理，从而在提升速度的同时显著降低功耗。

在测试环节，三星以参数规模达80亿的Meta开源AI模型Llama 3.1为基准，结果显示LPDDR5X-PIM的处理时间为5.4秒，较普通LPDDR5X的12.3秒快了约2.3倍；每秒令牌处理量达81.3 TPS，为现有产品27 TPS的三倍。事实上，三星早在2021年便公布了面向高带宽内存的HBM-PIM技术并完成开发验证。

三 | 此次将PIM落地于智能手机等移动设备广泛采用的LPDDR低功耗内存，正是顺应大语言模型向小型化、高效化演进的新趋势。 相关负责人指出，虽然HBM是目前AI内存的标准方案，但并非所有场景都非它不可，LPDDR-PIM兼具高带宽与低功耗，为端侧AI开辟了新的可能。

随着生成式AI直接在智能手机、PC等终端设备上运行的端侧AI趋势不断扩展，LPDDR-PIM的应用前景持续看涨——电力与空间受限的移动设备，亟需在提升AI算力的同时严控功耗。在兼容性方面，该产品沿用与通用LPDDR相同的阵列设计，无需大幅改动系统即可部署。目前，三星正提供软件开发工具包和模拟器等资源，积极推动生态建设。继LPDDR5X-PIM之后，三星已启动LPDDR6-PIM的标准化工作，AI内存竞争正从以HBM为中心的数据中心，延伸至智能手机和PC等端侧领域，内存也正从单纯的数据存储设备，向直接参与运算的关键组件演进。
