During my internship at the Jiangsu Center of Xinhua News Agency' s News Information Center, I leveraged my video production expertise to create two high‑quality video ringback tones for Hengshun Vinegar. One of them, titled "Hengshun Promotional Film: Industrial Heritage – The 'Living Fossil' of Vinegar Brewing," highlights the brand' s century‑old history and the cultural essence of its brewing craft, and was provided to Hengshun Vinegar for new‑media brand promotion.
