How do you write merry x mas in Chinese but engilish?

You can write "Merry X Mas" in Chinese characters using the English pronunciation. This is called "pinyin" and is the most common way to write English words in Chinese.

Here's how it would look:

美利 耶诞 (Měilì Yēdàn)

* 美利 (Měilì) means "Merry"

* 耶诞 (Yēdàn) means "Christmas"

You can also write "Merry Christmas" in Chinese using the traditional characters:

聖誕快樂 (Shèngdàn Kuàilè)

* 聖誕 (Shèngdàn) means "Christmas"

* 快樂 (Kuàilè) means "Happy"

Both options are correct and commonly used.
