Bustling Dongshi (East Market) and Xishi (West Market), two major commercial hubs in the former imperial capital of Chang'an — today's Xi'an in Shaanxi province — were also re-created based on historical records. Their buildings vary in height, creating a dynamic skyline, and the shops are densely packed together.

To enhance the lively street atmosphere, foods popular at the time, like steaming hot sesame cakes and noodle soup, are included to add a touch of authenticity to scenes.

The lighting is even more accurate, with Ding primarily using torches, kerosene lamps, and candles to illuminate nighttime scenes. This makes the series feel more authentic, as if it is a true reflection of the China of over 1,000 years ago.

Costumes, makeup and props are a crucial part of the creative process, and convey a wealth of information that doesn't need to be expressed through dialogue. Drawing inspiration from artifacts displayed in museums in Luoyang in Henan province and Xi'an, the prop department made exquisite pieces of jewelry props and more than 1,500 outfits.

"When the actors were on set using the props and dressing like people from the Tang Dynasty, it helped them immerse themselves more deeply in their roles," the director says.

For art director Long Ya, Tang-style costumes are a splendid chapter in the history of ancient Chinese attire, characterized by their opulence, vibrancy, boldness and flair.

To make a feature of fashion at the time, Long says they drew inspiration from Sancai, or tri-colored pottery, as well as the Dunhuang murals in the Mogao Caves in Gansu province.

Unlike most previous period dramas set in the era, the female characters do not wear earrings — a detail that sparked heated debate on social platforms such as Sina Weibo.

Long explains that based on their research, people during the Tang Dynasty followed Confucian beliefs, which posit that the body is a gift from one's parents and should not be harmed. "As a result, few people pierced their ears or wore earrings," Long says. "But it was fashionable for men to adorn their hats with flowers. We've incorporated these historical details into the show."

Ceremonies are also meticulously re-created. For example, in He's wedding scene, she gracefully holds a round fan to shield her face before stepping into the bridal chamber with her groom. The couple also cut a lock of their hair and place it in a pouch, symbolizing their lifelong bond.

Long also says that they recruited a horticulturist to show them on how to properly water peonies and care for them when they wilt.

Ding expressed his delight that more international viewers were getting a glimpse of the beauty of the Tang Dynasty — a glorious, prosperous era that had a profound influence during its time.
