Never Leaving the Group Chat

"HVAC is a low-frequency, long-chain, service-heavy industry."

Zhang Shun has always had a clear-eyed view of the business. Low-frequency means a single decision carries consequences for years. Long-chain means every small mistake can magnify over time. Service-heavy means the job isn’t done when installation ends—it’s just the beginning.

He has a habit many peers consider cumbersome: he never leaves a client group chat.

"Whether a client worked with us five or ten years ago, we stay with them to solve any issue." Even at midnight, if a client reports a hot water failure—whether or not it’s within Rongchu’s scope—Zhang responds first and seeks solutions immediately.

To him, clients are often not technically savvy. Losing hot water at night is helplessness, and stepping in—even beyond obligation—distinguishes service from mere business. It’s also the soil in which a decade of trust grows.

Those Who Understand Life, Understand Home

Approaching 40, Zhang Shun is in a midlife recalibration. Once career-driven, he now prioritizes health and family. He invests in his children’s education and habits, and no matter how busy, he reserves energy for home.

A professional who values life and family often designs systems that feel warm. Understanding a child’s delight crawling on the floor drives him to focus on eco-friendly standards for underfloor heating. Awareness of elderly sensitivity to seasonal change pushes him to create comfortable environments. He doesn’t blindly follow “three-constant, five-constant” formulas, but tracks the essential data—temperature, humidity, oxygen levels—for healthy living.

He avoids overcomplicating or overpricing. Instead, he offers what fits a family’s lifestyle best—a blend of expertise and empathy.

The Tacit Understanding Among Experts

Reflecting on a ten-year collaboration with Earthmother, Zhang sums it up in one word: pragmatic.

"Earthmother’s greatest contribution was turning seemingly trivial underfloor heating accessories into an industry standard." In the past, these materials were overlooked. Earthmother improved environmental and safety standards while systematizing solutions to simplify homeowners’ experiences.

"Earthmother are doers, and so are we," Zhang says with a smile. No fancy words, only shared pragmatism. This alignment ensures products and services seamlessly integrate over a decade, creating invisible yet tangible peace of mind for homeowners.

Steadfast in a Changing World

What does the future market hold? No one knows for certain. Yet Zhang is confident:

"As long as I’m at the table, running operations and service solidly, the impact of any storm is smaller."

In an unpredictable world, pragmatism is a rare luxury. It reflects clarity amidst trends, respect for hidden work, and a ten-year commitment to every home’s comfort.

Earthmother is honored to work alongside partners like Zhang Shun. We believe those who act calmly and steadily will navigate cycles and enter their next golden decade.

Because pragmatic, they are reliable. Because consistent, they are destined for lasting success.
