The first thing I did was use the brush tool (B) with a small diameter, foreground color set to white, and erased the original text. Your best bet now is to redraw what you think the detail should be underneath. In this case for the first area of text that is pretty easy to figure out it's just a bunch of lines for the windows. But in the second area there isn't a lot to go on so I had to make some assumptions. Here is the original image the arrows indicate the text that has to be removed.
What I did was use the line tool (U) (Shift + U to cycle through the tools) to redraw the lines at 1px. In the area of the tree I used the clone tool with a very small brush size and picked several locations as my spot to clone from. Then I used the brush tool (B) at 1px to draw the outline of the tree which was covered with text in the original image.
This is a screen shot from Photoshop showing a few things to look at when using the clone tool (S).

The last step was to place the English text on the image. I placed the text to the best effect to cover any bad spots of editing if there are any. Since this text is going to cover parts of the drawing I used the stroke function on the text layer at 2px with white as the stroke color. More on how and when to use stroke can be found here.
