Here, winding paths lead to secluded places; Here, the green shade comes into view; The fragrance of flowers fills the air here; The small river is gurgling here; Here Hsinchu and azaleas accompany each other; Here 'auspicious clouds' and' jade '; Buddhist language "," late contemplation "," musical composition "; Here, the pink peach blossoms, pink and white red leaves, plum blossoms, golden bars, and red birch trees are scattered throughout the mountains and forests, dyed in red. The fountain pours down here, and koi fish roam freely; Here, copper bells ring, a hint of Sanskrit sound seeps into the heart, washing away the frivolity and restlessness of modern cities; Here, one window and one scenery, changing scenery with each step; Here, thoughts fly into the distance, hands fly away on the keyboard, and work turns out to be so joyful... Listening to the sound of flowing water in the office and watching the joyful parade of "a house full of gold and jade". Walking by the Jinyuan River, with rippling blue waves and lotus ponds, standing tall and elegant; A bamboo flute plays leisurely, and a few cuts of preserved plums bloom proudly in the snow; In front of the reed marshes, there are a few lines of melancholy. Who is singing softly: climb the tall building alone, gaze at the endless road, and fight a few more times? This is the employee culture that has always been advocated - happy work, colorful life. There is a kind of fate called Buddhist philosophy, from the persistence of flowing water from childhood to the gratitude of the Little Spirit Mountain Pagoda; There is a kind of heaviness called sharpening, starting from simple social responsibility; There is an emotion called closeness, from concrete jungle and hard work to working in the garden and a happy life; There is a value that deserves to be treated well - beneficial to society, beneficial to the company, beneficial to shareholders, beneficial to employees, and beneficial to oneself. Is this in heaven, or in the United States or Japan? This is Dongjin International Building, a 20000 square meter office building that creates miracles every day. Many world firsts will be born here. If you don't believe me, come and take a look. You will be more amazed and shocked, and you will be more unable to resist and have a more petty bourgeois atmosphere than me. Perhaps it's just because I took one more glance at you in the human world... This is the Shanghai headquarters of Pu Zhi
