French language Q&A Forum

After studying these lessons I don’t understand why, for example,

Vous vous aimez promener ici? Is wrong!?

And

Vous aimez vous promener ici? Is correct.

Je M'appelle Jordan, Je viens du Texas!

Is this an exception to the "h" rule that "le hautbois / du hautbois" is not "l'hautbois / de l'hautbois"?

In the explanation of this lesson page, there is a N/B: 

ATTENTION: you cannot use preposition + quoi, either for living or non-living things. Only the options above are correct in French. 

However, I have found a sentence «C'est ce à quoi je pensais» - is this not an example of 'preposition + quoi' ?

Please can you explain why I can't use Le Samedi at the beginning of the sentence is wrong, yet in the explanation Le is being used!

Or 

"Oh Je l'ai regardé aussi hier"
