Could you please explain what these words mean and transcribe them in Chinese script?
The word 欢迎 means welcome and is typed as huan ying. This is a pretty basic word in Chinese so you can easily look it up even via a quick Google search.



In case you encounter a similar case down the road...

If you use macOS or iOS, you can add a handwritten Chinese keyboard, and write the character in the screen by handwriting it. Then tap on the correct character on the pop-up and search it via Google, or paste it on the dictionary (macOS has a default Chinese dictionary, for your information).

If you use iOS and download an app called Pleco (which is available in Android as well), you can use the handwritten feature and dictionary together via an In-App Purchase.
