Dragon Boat Festival 2026
Riding the Current, Seeing Deeper
Wishing you a joyful Dragon Boat Festival from the GRANFOO team — and sharing what’s new in underwater vision technology.
端午安康 — Dragon Boat Festival Greetings from Granfoo
Xi’an, Shaanxi, China — June 17, 2026. The fifth day of the fifth lunar month marks the Dragon Boat Festival (Duanwu Jie), one of China’s most time-honored traditional celebrations. Observed for over 2,000 years, this festival commemorates the patriot poet Qu Yuan and is a time for families, communities, and businesses to pause, reflect, and extend warm wishes to those around them.
On this auspicious occasion, the entire team at Shaanxi Granfoo Intelligent Technology Co., Ltd. extends heartfelt Dragon Boat Festival greetings to all customers, distributors, partners, and friends worldwide. May your homes be filled with the fragrance of zongzi (sticky rice dumplings), your hearts lifted by the thunder of dragon boat drums, and your enterprises powered by strength, clarity, and purpose.
Just as Qu Yuan devoted himself wholeheartedly to the protection of his homeland, Granfoo dedicates itself to protecting urban infrastructure through precision inspection technology. We believe that the hidden arteries beneath our cities — the pipes, drains, wells, and conduits that sustain modern life — deserve the very best in monitoring and care. That commitment drives everything we do.

The table below summarises the key technical parameters across Granfoo’s three product families, enabling quick selection based on application needs:
Product Family 1: Portable Pipe Camera Systems
