"The core of their lives revolves around boats, and when they discuss buying a boat, the gravity is akin to how we city dwellers talk about buying an apartment," says Zhang.
During their survey journey through cities such as Huai'an and Yangzhou, Zhao recalls meeting young people who had graduated from foreign colleges and returned to their hometowns to start small businesses, such as opening bookstores.
"We heard many interesting stories and incorporated some of their elements into the drama," Zhang adds.
The series' major scenes are set in Huajie (Flower Street), a riverside community home to 18 characters from six families. To find the perfect filming location, the crew surveyed multiple sites before selecting Bacheng Old Street in Kunshan — a 200-meter-long, narrow street lined with densely packed, gray-tiled houses.
"Although filming on a sound-stage makes it easier to control lighting and the surrounding environment — such as avoiding onlookers — we chose to embrace the challenges of shooting on location and built the characters' homes directly on the street," says Zhang.
This also makes the filming feel more authentic, and full of everyday life. In some long takes, the scenes capture lively children joyfully running from their own courtyards to their neighbors', a bustling wonton stall opening for breakfast and residents sitting on small stools, enjoying their morning meals.
Interestingly, the construction work was kept on to ensure that the props and room decorations updated according to economic and societal development of the times, especially as local families' lives improved following the canal's successful bid for UNESCO's list, which has boosted local tourism and cultural businesses, according to Zhang.
The drama also explores the theme of root-seeking, according to the director.
Ma Siyi, one of six children living in Huajie, is a descendant of the Italian explorer's brother and his Chinese wife. After years of struggling with her appearance and background, she embarks on a journey to Italy in one episode to trace her roots. Raised by her Chinese grandmother after losing her father at a young age, her story highlights the quest for identity.
Similarly, in the final episodes, her five close friends, who mostly move to Beijing after growing up, return to their hometown, symbolizing their own journeys to reconnect with their roots.
"It has been a timeless literary theme revolving around 'who I am' and 'where I come from'. Until the end of the drama, the audience will see how all the characters' fates are bound to their ancestors from over 100 years ago," says Yao.
"Personally, this is the most captivating part of the tale and the reason it has drawn me to adapt it into a TV drama," he adds.
