The annual Mid-Autumn Festival comes slowly with the moonlight when the light shines all over the world and the osmanthus fragrance lingers in the streets. As a traditional festival of the Chinese nation second only to the Spring Festival, the Mid-Autumn Festival is not only a warm moment for family reunion, but also an important carrier carrying thousands of years of history and cultural wisdom. Every custom and legend tells the Chinese people's deep yearning for "reunion" and "perfection". ​

Today, the autumnal equinox arrives gracefully. This solar term divides day and night equally, as well as winter and summer equally, and nature exhibits a wonderful and harmonious balance at this time. There is a saying among the people that "white dew comes early, cold dew comes late, and it is the right time to sow wheat in autumn", which shows its important position in agriculture. ​

In the golden September, the fragrance of osmanthus flowers fills the air. In this season full of gratitude and respect, we welcome the 39th Teacher's Day. When we pay high respect to the teacher in front of the three foot podium, we cannot help but think: in different fields, are there also a group of "guardians" who silently guard the stability and development of a "world" with professionalism and perseverance? For Rosewool Insulation Refractory Co.,Ltd, we are the "temperature guardians" in the industrial field - using high-quality products such as high temperature resistant thermal insulation rock wool and aluminum silicate ceramic fiber needle punched blankets to safeguard the safe operation of boilers, kilns, and pipelines, just as teachers safeguard the growth path of students, conveying "warmth" with ingenuity and building "defense lines" with responsibility. ​
The protection of teachers is to guide them patiently in the classroom, using knowledge to build a ladder for students' growth, so that every dream can flourish under the correct guidance. The protection of Rosewool is to use professional insulation refractory products in the "classroom" of industrial production to build a safe "insulation barrier" for boilers, kilns, and pipelines.
