In the culinary landscape of Hangzhou – a city celebrated for its misty hills, ancient temples, and the shimmering waters of West Lake – few dishes carry as much cultural weight as West Lake Water Shield Soup (西湖莼菜汤). Known locally as “Chicken and Ham Water Shield Soup” (鸡火莼菜汤), this humble yet elegant dish is one of Hangzhou’s most cherished culinary treasures. It has been served to emperors and poets, graced state banquets, and – perhaps most remarkably – inspired a government official to quit his job and return home over 1,700 years ago.
What’s in the Bowl?
At its heart, West Lake Water Shield Soup is a study in simplicity and elegance. The star ingredient is water shield (莼菜, chuncai), a delicate aquatic plant that grows in the shallows of lakes and ponds. Harvested in spring and summer, its tender young leaves and curled shoots are prized for their smooth, gelatinous texture – a natural coating that gives the soup its signature silky mouthfeel.
The water shield is gently simmered in a clear, savoury broth made from chicken stock and garnished with shredded Jinhua ham and shredded chicken breast. The finished dish is a feast for the eyes: emerald-green water shield, pure-white chicken, and rosy-red ham create a tricolour composition as beautiful as the lake itself. The flavour is delicate, refreshing, and deeply savoury – a perfect expression of Zhejiang cuisine’s philosophy of letting premium ingredients speak for themselves.
The “Water Shield Longing” – A 1,700-Year-Old Story
The true magic of this dish lies not in its ingredients, but in the story it carries. According to the Shishuo Xinyu (A New Account of Tales of the World), during the Western Jin dynasty (265–316 AD), a scholar named Zhang Han (张翰) – also known by his courtesy name Zhang Jìyīng – was serving as an official in Luoyang, the imperial capital.
One autumn day, as the wind began to blow, Zhang was overcome by a sudden longing for the flavours of his hometown in the Jiangnan region. He thought of the water shield soup and perch sashimi he had enjoyed as a young man, and he declared: “Life is about following one’s heart. Why should I travel thousands of miles away from home just for a title and fame?”
With that, Zhang resigned his post, packed his bags, and returned home – all for a bowl of soup.
This story gave rise to the enduring idiom “water shield and perch longing” (chunlu zhi si), which has come to symbolise homesickness, nostalgia, and the choice to prioritise personal fulfilment over worldly ambition. For centuries, the dish has carried this emotional weight – a taste of home for those who have travelled far.
Poets and Emperors: A Dish for the Ages
Zhang Han was not the only one captivated by water shield soup. Over the centuries, some of China’s greatest literary figures have sung its praises.
The Tang dynasty poet Bai Juyi (白居易), who served as a governor in Hangzhou, wrote: “I still have a craving for perch and water shield – come spring, I may journey east to Jiangnan.” The Song dynasty poet Su Dongpo (苏轼), another Hangzhou governor and a legendary gastronome, celebrated the dish with the line: “If you ask about the finest delicacies of the three Wu regions, none surpasses a thousand-li journey for a bowl of water shield soup.”
The Southern Song poet Lu You (陆游), a self-proclaimed “super fan” of water shield, wrote evocatively of its silky texture: “The water shield shreds glide like silk, smooth and flowing.”
By the Qing dynasty, the dish had caught the attention of the imperial court. The Qianlong Emperor (1711–1799), famous for his six southern tours, made it a ritual to enjoy a bowl of water shield soup every time he visited Hangzhou. According to one account, he even composed a poem during his travels: “Flowers fill Su Causeway, willows veil the mist – when I gather water shield, the sun is bright.” Water shield was designated a tribute item for the imperial court during the Southern Song dynasty, when Hangzhou served as the capital.
A Modern Classic
In 1956, West Lake Water Shield Soup was officially recognised as one of the 36 classic dishes of Hangzhou by the Zhejiang provincial government. In 2009, the dish was further honoured when its traditional cooking techniques – along with other iconic Hangzhou dishes like West Lake Vinegar Fish, Dongpo Pork, and Longjing Shrimp – were inscribed on the Zhejiang Provincial Intangible Cultural Heritage list.
Today, the dish has taken on new meaning. For overseas Chinese and those living far from home, ordering a bowl of West Lake Water Shield Soup is a way of reconnecting with their roots – a culinary gesture of homesickness that echoes Zhang Han’s ancient longing.
Where Does the Water Shield Come From?
While the dish is called “West Lake Water Shield Soup,” the water shield is no longer harvested from West Lake itself. Historically, the aquatic plant was cultivated in the lake and surrounding areas – records in the Ming dynasty West Lake Travelogue (Xihu Youlan Zhi) note that water shield grew near the lake’s Third Bridge. The primary growing area shifted to Shuangpu Town in Xihu District, where water shield had been cultivated for nearly a thousand years.
However, due to urban development and environmental changes, the Shuangpu fields gradually shrank. In 2015, a Hangzhou native named Lu Shefu (陆社福), concerned that this treasured ingredient might disappear, relocated the cultivation to Wulong Village in Hangtou Town, Jiande – about 150 kilometres west of Hangzhou. Today, this is Zhejiang’s largest water shield farming base and one of the province’s protected germplasm resource sites. The base produces around 45 to 50 tonnes of water shield annually, supplying classic restaurants like Louwailou, Xizi State Guesthouse, and Xinxin Hotel.
Water shield is now graded by quality: L-grade (curled young leaves, most commonly used in restaurants), S-grade (pure tender shoots), and M-grade (unprocessed bulk). The harvesting season runs from April to mid-October, and the work is demanding – pickers spend hours each day in small boats or large basins, carefully plucking the slippery, gelatin-covered shoots from beneath the water’s surface.
Where to Taste It in Hangzhou
If you’re visiting Hangzhou and want to taste this legendary soup for yourself, here are some of the city’s most celebrated establishments:
- Louwailou Restaurant (楼外楼) – Perched at the foot of Solitary Hill on the northern shore of West Lake, this 178-year-old “China Time-Honoured Brand” (founded in 1848) is the undisputed home of Hangzhou’s classic dishes. Of the 36 dishes recognised in 1956, ten came from Louwailou’s kitchen – including West Lake Water Shield Soup.
- Xizi State Guesthouse (西子国宾馆) – A prestigious hotel that serves a refined version of the soup, sourcing its water shield directly from the Jiande base.
- Xinxin Hotel (新新饭店) – A historic hotel at 56–60 Beishan Street, known for its classic Hangzhou cuisine.
- Zhiweiguan (知味观) – Founded in 1913, this time-honoured establishment has been serving Hangzhou snacks and dishes for over a century.
For the most authentic experience, order the soup during spring or early summer, when the water shield is at its freshest and most tender. And as you lift your spoon, remember: you’re not just tasting a soup – you’re tasting 1,700 years of history, longing, and the enduring spirit of a city that has been perfecting this dish for generations.
