1、The traditional Chinese character 著 is equal to simplified Chinese character 着。Many books describe '著/着' as 'aspect particle' , which is put after a verb and should be called ‘虛詞/function word without no real meaning’, here indicating a state or the continuation of a state.
Here are some examples.
窗戶+開著。The window is/was open.
山上+覆蓋著+厚厚的+積雪。The mountain is/was covered with sick snow.
2、Another use of '著/着' is 'continuation of some action'.
他正吃著午飯... He is having his lunch.
風輕輕地吹著... The wind is blowing gently.
他提著箱子走進了那個房間。He went into the room carrying his suitcase.
