Tourists stroll and cycle around the spot, where limpid waters, lush mountains and blooming flowers combine in weaving a picturesque scene.
The delicate blossom seen floating there is Ottelia acuminata, an aquatic plant endemic to China, which is known to have extremely strict water quality requirements. It demands high water transparency, cleanliness and calcium content, and survives only in unpolluted waters, serving as a reliable natural indicator of aquatic ecological health.
Its large-scale revival vividly testifies to Erhai Lake's remarkable ecological restoration achievements.
China's Ecological and Environmental Code, enacted on Saturday, stipulates nationwide protection and restoration of river and lake ecosystems, providing solid legal support for systematic water ecological governance across the country.
As China advances its Beautiful China initiative, this code is expected to strengthen rule-of-law guarantees for ecological protection and provide fresh impetus for the country's green and low-carbon transition.
In the early 1990s, agricultural pollution worsened Erhai Lake's water quality, causing frequent blue-green algae outbreaks. A severe algae bloom hit the lake in 1996, leaving the water turbid and smelly. As the environment degraded, Ottelia acuminata nearly disappeared from the lake.
Thanks to years of targeted ecological protection and restoration efforts, the lake's water quality has improved steadily, maintaining an excellent Grade II standard from January to June 2026, and creating favorable conditions for the return of Ottelia acuminata.
Official data show that the plant's coverage on Erhai Lake has surged from 90,000 square meters in 2021 to 950,000 square meters in 2026, marking a remarkable ecological recovery.
The improved water environment has also brought tangible economic benefits, turning the lake's ecological advantages into a sustainable industry. From lake ecology to farm cultivation and consumer products, Ottelia acuminata's dual ecological and economic value has been fully realized.
In 2018, environmental worker Zhong Lan noticed the edible plant's great potential for water purification and industrial development. With support from local authorities and Shanghai Jiao Tong University in eastern China, she started a company and built a professional research base in 2024, developing standardized planting techniques that enable high-yield, repeated harvests and offering jobs for local villagers.
Villager Li Xinyuan, who quit Ottelia acuminata cultivation years ago due to low profits, resumed planting in 2023 and earns a stable monthly salary of 4,500 yuan (about 663 U.S. dollars) at the base.
His fellow villager Du Hongquan earned over 100,000 yuan last year from growing the plant and has more than doubled his planting area this year. "The base takes full charge of sales, so we can plant without any worries," Du said.
Eryuan County, the source of Erhai Lake, now has more than 200 hectares of Ottelia acuminata plantation area, creating numerous jobs yearly. The plant has been developed into a diverse range of products like tea, plant-based coffee and cookies.
"I used to think it was exclusive to Yunnan, but I can try it elsewhere too," said a tourist surnamed Ai after tasting the plant at a hotpot restaurant in Hangzhou, east China's Zhejiang Province.
The beautiful lakeside scenery at Erhai has also boosted local tourism. In 2025, Dali received over 120 million tourist visits, attracting visitors to enjoy lake views and experience local Bai ethnic culture, with 407,000 long-term visitors.
Last month, the State Council issued a plan for building a Beautiful China during the 15th Five-Year Plan period (2026-2030), setting out the overall requirements, targets, key tasks and major projects for comprehensively advancing this initiative.
According to the plan, China will achieve overall improvement in ecological and environmental quality and make significant progress toward building a Beautiful China by 2030, with green production and lifestyles largely established and the carbon peaking target reached on schedule.

    　　ClutchPoints 记者 Brett Siegel 撰文，解析了詹姆斯-哈登休赛期的续约前景。

    　　报道直言，哈登会继续留在骑士阵中，如果这名 11 届全明星、前 MVP 有意改换门庭，休赛期早已经完成转会操作。8 月 26 日哈登即将迎来 37 岁生日，这很大概率是他职业生涯争取长期保障合同的最后窗口期，他确定会和骑士签下新合约，只是薪资数额还没有最终落定。
    
    　　骑士现阶段正全力追求佩顿-沃特森以及库明加，哈登愿意将续约谈判暂时延后，以此为球队保留薪资操作余地。对比他上一份合同 2026/27 赛季 4230 万美元的年薪，哈登将会选择降薪，目的是帮助球队围绕自己和米切尔搭建更强阵容，前提是骑士能够成功引进沃特森或者库明加其中一人。
    
    　　双方有可能等到哈登生日当天敲定签约细节，也有可能谈判延续到 9 月。但无论谈判节奏快慢，哈登都会在 9 月底训练营开营之前和骑士达成续约，不会转投其他队伍。新合同年薪预计落在 2500 万-3200 万美元，这一较大浮动区间，取决于骑士能否完成上述目标球员的交易。
    
    　　该记者判断，休赛期其他球队并没有向哈登抛出橄榄枝，骑士就是他的最优落脚点，双方将会签下一份新的长期合同。
    
    　　回顾上赛季，哈登被交易至骑士之后常规赛出战 26 场，场均出场 33.8 分钟，交出 20.5 分 4.8 篮板 7.7 助攻；季后赛出战 18 场，场均 37.3 分钟，贡献 19.2 分 5.1 篮板 5.5 助攻 1.7 抢断，助力骑士闯入东部决赛。
