Don't talk about the fact that the person is dying. Try to bring up a happy memory for them or talk about yourself.
Ti Tzu Kui (simplified Chinese: 弟子规; traditional Chinese: 弟子規; pinyin: Dìzǐ Guī; Pe̍h-ōe-jī: Tē-chú-kui, Standards for being a Good Pupil and Child) was written in the Qing Dynasty during the reign of the Kangxi Emperor (r. 1661-1722) by Li Yuxiu. The book is based on the ancient teaching of the Chinese philosopher Confucius that emphasises the basic requisites for being a good person and guidelines for living in harmony with others. Like the San Zi Jing (another classic Chinese children's text), it is written in three-character verses. The source for the main outline of it is from Analects of Confucius, Book 1, Chapter 6, where Confucius said:
A young man should be a good son at home and an obedient young man abroad, sparing of speech but trustworthy in what he says, and should love the multitude at large but cultivate the friendship of his fellow men. If he has any energy to spare from such action, let him devote it to making himself cultivated. Express Yourself
