First, look at the year and month. The fake Tetuo is basically from April 2004. The second is to look at the shelf life. Before 2006, Xiaguan had a shelf life of 36 months. In 2004, if I saw that there was no shelf life and could be stored for a long time, it must be fake. The third is to look at the Tuo noodles, the characteristics of the materials used, the tightness of the pressing, etc. Many Laoxiaguan camellia oils can be fake at first glance.

Common knowledge on identifying authentic and fake Xiaguan Tuocha. Grade A Tuocha: Grade A Tuocha is the conventional product with the longest production time and largest output in Xiaguan factory. After Grade A Tuocha was put into production in 1951, it has continued to be produced to this day. Early Grade A Tuocha came in two specifications: 250g and 125g; after the 1970s, it was replaced by the now common 100g specification (but due to order requirements, special-weight Tuocha was also produced in small quantities). Grade A Tuocha, with a height of about 4.3 cm and an outer diameter of about 8.3 cm, used the "China Tea" trademark in the early days. Since 1992, the "Songhe" trademark has been registered. In 1992, the registered trademark Songhe Tuocha (domestic sales) was officially launched. (Very important) In 1996, the tea factory decided to use the factory emblem as a product logo and stamp it on Grade A Tuocha tea to replace the word "A" that was originally stamped on Grade A Tuocha tea. (More important) In 2008, there was no factory version. Of casual and boxed Jiatuo, there is only one FT customized green box Jiatuo. Special-grade Tuocha: The Xiaguan Tea Factory started producing special-grade Tuocha in 2003 due to orders from merchants. The size of the tea is 100 grams, the height is about 4.3 cm, the outer diameter is about 8 cm, and it uses the Songhe brand. The outer packaging is packaged in laminated paper bags and single-piece red boxes. First produced in 2003. In May 2004, I was approved for red eyes. In 2008, neither casual nor red-box special-grade Tuocha was released. Jinsi Tuo Tea: Xiaguan Jinsi Tuo and Xinye completed the first batch of Jinsi Tuo Tea customized in Xiaguan in March 2004. The old packaging is beige in color and is a red-eyed crane. The Jinsi Tuo Tea made after August 2004 uses The new packaging is called Jinsituo because there is a gold ribbon inside the tea. In March and May 2004, I received approval for red eyes. Not shipped from the factory in 2008.
