Chinese people rarely ever say "have a wonderful day", so the only phrase with about the same meaning would be 祝你安好 (zhù nǐ ān hǎo), which means "I wish you well". This is also a farewell saying.
Hello, you beautiful.
it's a beautiful day: 这是一个美好的一天/Zhè shì yīgè měihǎo de yītiān
Beautiful is 美, pronounced Mae. The pinyin is mei. Another way to say beautiful in Chinese is 美丽, pronounced Mae-lee. The pinyin is mei li.
You simply don't say that. Death is not considered to be beautiful. Talking about death that way is a taboo.
