OUR STORY

CONVERGE & HONESTY

“That all rivers converge and flow into the sea lies in the sea being lower than them.” -- Lao-tzu (philosopher, founder of Taoism)

“Converge” represents broad-mind. Being courteous and humble is how we attract experts and talents for better protecting the intellectual property of our clients.

“True in word and resolute in deed” -- Confucius (philosopher and educator)

Clients come first. The client’s goal is always ours.
“Honesty” is what we rely on to develop the work relationship with our clients.

This is How C&H comes from.
