Legend has it that the dragon has nine sons, and the ninth son is "Jiaotu". Its shape resembles a snail or clam, it likes to close up and enjoys quietness, and when faced with external threats, it always tightly closes its shell opening. People use it on doors to symbolize "tight closure" in hopes of safety.
　　"Tianchen Jiachuang" named its product "Jiaotu" and uses it as the brand image, hoping that "Tianchen Jiachuang" products can protect car owners like "Jiaotu", allowing them to have a safe and comfortable driving experience.
　　The English name for "Jiaotu" is "JOOTOON", which is a transliteration of "Jiaotu". The company also defines its homophone "Jiaotu" (meaning "Proud Journey") as the name for the new generation series of "Tianchen Jiachuang" products.
