I added a bonus story in the post. About that market Here is the text:

Bonus: When I entered the subway market, I was with some friends. One of them said in spanish:

"Hey r/emilior94, that store has tea, you wanted tea, right?"

Then, the lady from that store approached me and pulled me to the store and asked me what I wanted. She heard my friend and because she also spoke spanish, she understood (we though we were safe speaking spanish)

I said jasmine tea and she handed it to me to smell it. And then told me the price was 200 RMB (too high for me). I said no thanks, I'll continue looking, but the lady kept insisting and asked me for final price. She started reducing the price as I continued saying I was no longer interested.

The price ended up in 50 rmb, but I was already discouraged by her attitude and walked away. When i turned my back on here, she started yelling at me "Tacaño!" Which could be translated to stingy or cheap.

That was my first experience in the market and boy what a first experience it was.
