Maichi was produced by the former Henan Hester Oil-saving Agent Factory and was established before 2000. At that time, it also obtained a national patent, but it was n years ago. Maichi is just a small car bag they sold online in the past two years. The composition and technology should still be the same, so I personally feel relatively backward. Aladdin should be a novice in computing. He has done well in recent years, especially on Taobao. You can search. Neither the seller nor the buyer is on the same level.
Moreover, Maichi additive looks clear, orange, low concentration and smells close to gasoline; Compared with Michi, Aladdin's liquid is slightly viscous, reddish brown (different colors will be different due to different external temperatures), with high concentration and special smell.
