Company at a glance

Main businesses

The company’s official introduction brings together tea research, growing, production, sales, cultural exchange and the transmission of traditional tea-making skills. It describes domestic sales through e-commerce, wholesale, direct sales and agents, as well as overseas markets.

The production side is complemented by tea gardens and the China Qihong Science and Technology Expo Park, which the company describes as combining standardized production, warehousing, a tea museum, research, training and interactive experiences.

Representative products and collections

Qihong Guoli and Qihong Huangcha

The Qihong Guoli collection includes red and black gift-box versions and individual tins. The red gift-box product image identifies a 300 g pack comprising two 150 g tins, with the Chinese grade marked 特级. This is useful product-specific information when comparing a gift box with a single-tin option.

Qihong Huangcha is another named Keemun collection, also presented in red and black gift boxes and individual tins. The collection names and packaging give a starting point; the actual label provides the tea’s production date, specification and grade.

Qihong Xiangluo and other Keemun selections

The Qihong Xiangluo category lists Hongyao 8500, 3500 and 1500 gift selections and a classic single-tin product. The wider Keemun catalogue includes Expo commemorative tea, vintage collections, Qihong Gaoxiang, Qihong Xiangcha, Lixiang, Fucha, Mengzhihong and jasmine Keemun.

This is a range with several buying occasions, from a personal tin to a formal tea gift. Product names identify different lines; a numbered collection should be compared using its own specification rather than treating the number as a universal tea grade.

Huangshan Maofeng and Taiping Houkui

Although Keemun is the brand’s central story, its product navigation also includes Huangshan Maofeng and Taiping Houkui. Both sit in the company’s broader Anhui tea offering. They belong to a different tea category from Keemun, making the exact product selection especially relevant when buying for someone whose tea preferences are known.

Tea gardens and production background

The tea-base section names Baita, Baixi and an estate tea garden. In its company introduction, Tian Zhi Hong describes a model involving the company, family farms, growers and production bases, with standardized tea-garden improvement.

The company also describes certified organic production bases within its wider network. Buyers interested in organic tea should request the certification and scope for the particular product and supplier involved.

Research, standards and Keemun heritage

The company introduction describes engineering and enterprise technology centres, research projects and work on Keemun tea standards. It also highlights the transmission of traditional skills as part of the business. Together, these explain a model combining tea-factory experience, technical development and cultural interpretation.

For a buyer, this background becomes most useful when it leads to clear information about raw material, processing, grade and traceability for a named tea.

Tea tourism and the Qihong museum

The website introduces Tian Zhi Hong Estate as a tea-country visitor experience with gardens, bamboo surroundings, tea spaces and tea-making activities. Its museum and cultural facilities are presented as places to learn about Keemun production and tea history. Confirm current opening arrangements and any activity booking directly before visiting.
