[LilyLee]

Methods to identify the date of automotive glass: You can check the lower left corner of the glass, which consists of graphics, numbers, and English letters, including certification marks, glass type, production date, and other information. The numbers represent the year, and there are two rows of dots to the right of the numbers. The first row of dots represents the month, and the second row consists of two different shapes of dots. The first type of dot: one dot represents N days, two dots represent N plus 10 days, and three dots represent N plus 20 days. Automotive glass mainly falls into the following three categories: laminated glass, tempered glass, and zone-tempered glass, which can withstand strong impact forces. Automotive glass is divided into four types based on its location: windshield, side window glass, rear windshield, and sunroof glass.
