Warmly congratulate the successful convening of the 20th National Congress of the Communist Party of China. The grand and warm scene of the meeting and the inspiring voice of the times make the Chinese people excited with joy and longing! The country insists on people first, while enterprises need to insist on customer first; COBOL has been deeply involved in the printing consumables industry for 30 years, and has developed several measures to uphold the service concept of "customer first"!
