and he also sent messengers around central China, redistributing land to give the poor farming land. In 593, Emperor Wen commissioned a summer vacation palace, Renshou Palace (仁壽宮, in modern Linyou County, Shaanxi), away from Chang'an, with Yang Su in charge of the project. The palace was far more luxurious than Emperor Wen expected, and its construction cost many lives. (When it was completed in spring 595 and Emperor Wen visited the palace, he was initially very displeased with Yang Su, but Empress Dugu persuaded him that Yang Su knew that he had little other entertainment, and she awarded Yang Su much treasure to show appreciation.) Also in 593, knowing that the Princess Dayi was still resentful of him, Emperor Wen had the official Pei Ju inform the cousin and subordinate khan to the Göktürks' Dulan Khan, Ashina Yongyulü, the Tuli Khan Ashina Rangan (son of Ashina Chuluohou) that he would let Ashina Rangan marry a Sui princess if Ashina Rangan was able to get Princess Dayi killed. Ashina Rangan, in response, accused Princess Dayi of adultery, and Ashina Yongyulü killed her and requested another marriage with Sui. Instead, Emperor Wen agreed to marry a princess to Ashina Rangan, in order to create greater friction between them. In 594, in response to another famine in the Guanzhong region, Emperor Wen again temporarily took up residence in Luoyang. He also, to share in some of his people's suffering, abstained from meat for a year. Late in 594, Yang Guang submitted a petition that Emperor Wen carry out the ancient ceremonies of worshipping the heaven and earth gods at Mount Tai. Emperor Wen declined to carry out a full set of ceremonies due to its costs, but in spring 595 carried out an abbreviated version to seek blessings from the gods due to the ongoing drought. Also in spring 595, Emperor Wen ordered that no weapons be held by private individuals and that all of them be collected and destroyed, although he exempted the border provinces from this edict. In 596, Emperor Wen created a daughter of a clansman the Princess Guanghua and married her to Murong Shifu, to cement the peaceful relations with Tuyuhun. In 597, Cuan Wan (), the chief of the Nanning Tribe (南寧夷, located in modern Qujing, Yunnan), rebelled. Emperor Wen sent the general Shi Wansui () the Duke of Taiping against Cuan, forcing him to surrender. Initially,
