Cool-looking bronze bottle vase.
The marks are for the Qing Dynasty Emperor Quianlong, who ruled China between 1735-1796 and then a further three years as Emperor emeritus following his abdication (out of respect, to avoid reigning longer than his grandfather’s 61 years as Emperor).
Below is the correct orientation for the marks, and the characters are then read top to bottom and right to left. Although the marks on bronzes especially are highly stylised as is the case here, I read them as “? ? Zhi Quian Long”, as per the reference chart I’ve shown alongside.

The first character I don’t recognise but will likely be a town/workshop/maker mark since the second character “Zhi” means “make” (in the sense of indicating where or by who it was made).
One thing to note about bronzes like this is that the marks are often not contemporary with the work itself. Traditional styles were copied in later times and it was common practice for the marks to be copied as well since they were deemed to be an integral part of the artistry. Perhaps in this case, the marks might genuinely be from the 1700s but it would need an expert to tell.
