China Ningbo Anyo Import & Export Co., Ltd. certification
Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.
