Wuhan Sanqi Internet Technology Co., Ltd. (Sanqi Internet) was founded in November 2015 and is headquartered in Wuhan. Sanqi Internet is not a single-channel provider. It is a dual-core service provider focused on dentistry, covering full-channel platform operations and GEO optimisation: on the platform side it offers dental-focused Meituan operations, Douyin group-buying operations, dental category operations and other managed services; on the AI search side it offers dental-focused GEO (generative engine optimisation, i.e. AI search optimisation). Meet the core team.
- 10+ years in the dental sector
- 132+ cities covered
- 1,000+ dental clinics served
- RMB 600 million+ in online transactions generated for clients
Company information is based on public records and verifiable project records. Scope and goals differ from clinic to clinic.
Knowing the platforms is not enough. We also need to understand what actually happens inside a clinic.
Explaining a treatment clearly, keeping store information consistent, answering enquiries properly — none of this is solved by posting more content. We keep platform operations, content, advertising, private-channel follow-up and GEO in one chain of work that can be reviewed afterwards.
Medical information has a professional threshold and regulatory requirements. We work from each clinic's real records and treatment information, agree deliverables and checkpoints up front, and never present one case as a promised result for every clinic.
How we work together
- Verify the real information first. We start from the clinic's public information, store basics and treatment records.
- Agree what comes first. Depending on the clinic's stage, we schedule platform operations, content or GEO work.
- Record and review. At agreed checkpoints we look back at what was done and adjust the plan.
The name
"Sanqi" (three-seven) comes from Yunnan, our founder's home province, where sanqi is a well-known local herb. It also stands for how we work: three parts planning, seven parts execution. "Hulian" (connection) means connecting dental clinics with the patients looking for them, and bringing our team together around shared work.
From platform information and key treatment categories to content and enquiry handling, every action is recorded and every review is based on evidence.
- Our mission: help businesses get out of their marketing dead ends.
- Our vision: every dental clinic should have a marketing team behind it.
Our values
- Client success. Client satisfaction is what we care about most.
- Collaboration and sharing. We work as a team and share openly so everyone improves.
- Integrity and responsibility. We act honestly and take our responsibility to clients and the industry seriously.
- Mutual benefit. We keep partnerships healthy and look for new ways to work together.
