1. The custom of giving red ties to students at the graduation ceremony of Guangdong University is not a common phenomenon, at least there is no clear record in the public information that there is such a tradition in Guangdong. However, in China culture, red is often a symbol of happiness, success and good luck. Therefore, red ties may be distributed in some special graduation activities to celebrate students' graduation achievements, suggesting that they can have a warm mental outlook and a positive future when they start a new chapter in their lives.

2. In addition, it is mentioned in the article that "during the Nanchang Uprising, leaders including Zhou Enlai, He Long and Liu Bocheng, as well as ordinary soldiers below, all wore red ties around their necks", which shows that red ties have specific political and symbolic significance in a specific historical background. But this is not directly related to the situation that Guangdong University graduates get red ties.

3. If there is a red tie in the graduation ceremony of colleges and universities in Guangdong, it may be because of the innovation of the school itself or some special cultural heritage, but there is no specific data to prove this. If there is such an activity, it should be a unique sense of ceremony established by the school according to its own characteristics and understanding of red culture.
