2,For the price agreement you mentioned, we signed this annual price agreement with your company every year, and we have been implementing this agreement . The price reduced a little each year since 2016, infact our profit is very low. This year is special,the raw materials increased so much, and our costs have gone up so much that we can't afford it. Therefore, I have no choice but to apply for price adjustment, hoping your company can help share a small part of the cost increase.
