2023 Mid-Autumn Festival and National Day Holiday Notice

-RO4003C 20mil Rogers PCB: High Performance and Reliability

Dear valued customers and partners,

We are pleased to announce that Bicheng Company will be taking a 7-day holiday break in celebration of the Mid-Autumn Festival and National Day from September 29th to October 5th, 2023. During this time, our office will be closed, and normal operations will resume on October 6th, 2023.

The Mid-Autumn Festival, also known as the Moon Festival, is one of the most important traditional Chinese festivals, symbolizing family reunion and harvest. It falls on the 15th day of the eighth lunar month, which this year coincides with September 30th, 2023. This festival is celebrated by gathering with family and friends, appreciating the full moon, and indulging in delicious mooncakes.

Mid-Autumn Festival

Following the Mid-Autumn Festival, China's National Day, which commemorates the founding of the People's Republic of China, is celebrated on October 1st, 2023. This holiday marks a significant period of national pride and unity.

During this holiday break, we encourage you to take this opportunity to spend quality time with your loved ones and create precious memories. We sincerely apologize for any inconvenience caused by the temporary closure and appreciate your understanding. Should you have any enquiry during the holidays, pls feel free to email to

Best regards,

Shenzhen Bicheng Electronics Technology Co., Ltd
