Post pandemic era, our team members enjoyed trips around China, from the Great Wall & Forbidden City in Beijing, the amazing ancient stone carving of Dun Huang, to the stunning landscape of Tibet and Qinhai, the panoramic view of South China sea in Hainan Island. Either with tourist group, parents or kids, we treasure the freedom of life after the plague, more than ever. Maybe the vacation is just a prelude of next chapter of hard trip, but it surely makes us more strong and our minds more purified, it reminds us of the words of Kant, the German philosopher, who said, "In this world, there are only two things convulsing our hearts heavily. One is the starry sky above our heads. Another is the lofty moral in our hearts.
