Just after the Spring Festival holiday in 2022, our company received orders for D-glucosamine from American customers. Customers' orders increased slightly from October 2021, and overall demand increased. The price of D-glucosamine continues to be stable, the sea freight dropped slightly from November to December 2021, but the freight continues to increase in 2022. Due to the continuous increase in sea freight, it has caused some trouble for us to quote customers. For most of foreign customers, they also understand this situation, and customers with relatively strong strength also have better countermeasures. For our company, we will continue to pay attention to the situation of sea freight.
