The head of "Tao Huabi" on the real bottle is clear, and the fake head is vague or haunted; The real' Laoganma' has a gradual change from golden yellow to red, while the fake' Laoganma' has the same color or uneven transition. At the same time, the authenticity can be identified from the production date and batch number. The production date and batch number of genuine products are uniform point inkjet, and the fake logo characters are irregular. In addition, the genuine Chili sauce has the handwriting of "Laoganma" at the bottom after the anti-counterfeiting mark is uncovered, and the anti-counterfeiting code consisting of 16 numbers is on the back of the film (each bottle is different). If it is difficult to uncover the fake Chili sauce, there will be no "Laoganma" after uncovering it, and the number 16 on the back of the film is the same set of numbers (the same for each bottle).
