The elf princess Thranvielle Yemai was tired of the tranquility of the Moon Creek Forest, and with a strong curiosity about the unknown, she stepped into the noisy human kingdom "Oak Town". She is keenly aware that the language gap between the two sides is not accidental, but stems from fundamental differences in the perception of time, space and even everything (Hofstede's cultural dimension). She used quills and crystals to carefully record the secrets of human beings patting shoulders, laughing, and averting their eyes (communicative ethnography), and tried to design a translation device that could understand "human humor" (the prototype of linguistic relativity). Conflict breaks out when human logging axes threaten the ancient trees that the elves consider kin. Thranweil did not choose to fight, but used her understanding of "human efficiency first" (cultural adaptation theory) to cleverly introduce the secret method of elves communicating with ancient trees to sense soil moisture and insect damage (tree communication technology), and transformed it into a "natural early warning device" to increase human farmland yields. In the process of establishing the "Where the Stars Meet" communication center, she relied on precise analysis of the stereotypes behind speech (sociolinguistic analysis) to resolve prejudices, and ultimately contributed to the prototype of the "Smart Racial Equality Convention".
