Personally, if you are a Korean classmate, don't send anything ~ if you are a familiar friend! Send some special handicrafts, of course, more famous handicrafts! You know Koreans know very little about China! So Chinese knots are so profound, forget it! Folding fans, then scarves and so on! Anyway, my gifts are all women, scarves and handkerchiefs! Male talk ~ China's tobacco and alcohol are also good ~!
Never send anything with a deep cultural level! After being in Korea for so long, I feel that the cultural level of Koreans is not very high! A little too westernized, I don't know what culture means! However, it is a good choice for older professors to send folding fans. At least our professor here is cute with a folding fan in his hand ~
