Liubiju yellow sauce tastes a little bitter, while the onion companion bean paste tastes milder. After adding some sweet noodle sauce, it tastes just right, and you don't need to put salt, sugar and monosodium glutamate. Therefore, the onion companion is delicious.

Congbanlv was founded in 1994, and was named after Shandong people's eating habits of dipping green onions in sauce.
