Company Culture

The corporate culture of Huitian Adhesive is the masterly generalization and summation of the team’s business creation course. It is a concentrated reflection of values and concepts of Mr. Zhang Feng, Chairman of the company. Huitian culture is the basis of Huitian. It includes one core (Human-orientation), four mechanisms (incitement, competition, elimination and supervision), four spirits (teamwork, innovation, devotion and hardworking) and four concepts (learning, calamity, honesty and thanksgiving).

1. One core- Human-orientation

Passion comes from love and business attributes in persistence.

Make competition promote two-way choice, realizing optimization.
Standardize operation with competition and implement price comparison. Refuse black case work in bidding for projects.

Elimination mechanism 
Elimination is a kind of ‘catfish effect’ which finally makes fishes much healthier.
Elimination makes antelope survive in the hostile environment.
Performance ranking, eliminate the last ones (for three times) and make who slack off watchful.
2% of dropout rate is the lifeline of Huitian.
If Huitian does not eliminate the losers, the market will eliminate Huitian.

Power must be balanced; supervision avoids corruption.
Supervision is just like the sunshine project to gather people's cohesion. 
Make employees know anything they should know.

Hardworking spirit
Huitian people walk to the market from sleeping on the floor, living in coach and selling in the street.
Struggling means never satisfied, indomitable, gritty, self-discipline and continuous improvement.  
Winners overcoming difficulties will never be short of courage.

The company keeps the promise to employees and employees keep the promise to customers.
Senior managers keep the promise to shareholders and Huitian keeps the promise to society.

Self-eliminated, or competition will eliminate us.
Thinking of danger in times of peace can make you calm down and turn danger into safety.
