Tang Dynasty: Si Zi's Modern Happy Journey

In the early morning of 2025 AD, a pair of wealthy siblings were playing on the rooftop of their manor when they unexpectedly met Princess Jinyang (nicknamed Sizi), the youngest daughter of Emperor Taizong of the Tang Dynasty who had traveled across time and space. This encounter was like a butterfly fluttering its wings, quietly changing the original life trajectory of Empress Changsun and several Tang princesses. The well-intentioned siblings decided to use modern knowledge and resources to provide Datang with weapon blueprints and engineering technology that transcended the times. With the support of advanced forces, the Tang army's strength increased by leaps and bounds, and its national power became increasingly powerful. After that, the two siblings participated in strategic planning to help the Tang Dynasty march eastward and pacify Japan in one fell swoop. As feedback and continuation, the siblings took Sizi and other princes and princesses through time and space to the modern world a thousand years later. The princes and princesses, who had never seen high-rise buildings, cars or electronic screens, were deeply shocked. They travel between cities, take the subway, experience amusement parks, enter science and technology museums, and come into contact with fashionable clothing in shopping malls. Interesting things continued during this period: the princes tried to summon the guards with their mobile phones, and the princesses exclaimed the magic of the automatic door. The siblings guide patiently along the way, explaining how modern society works. This encounter spanning thousands of years not only changed the partial flow of history, but also created a unique memory full of surprise and laughter in the exchange between the two time and space. The collision of ancient and modern thoughts finally settled into a warm and bright chapter in everyone's heart.
