The SKU data provided is different from what's already in the Amazon catalog. The item_id data provided matches ASIN XXXXX, but the following data is different from what's already in the Amazon catalog: item_name (Merchant: '我更新的标题' / Amazon: '我的品牌'). If this is the right ASIN for your product, update your data to match what's in the Amazon catalog. If it's not the right ASIN, make sure that your data for item_id is correct.
