Can someone help me to correct this text?  Thank you.

The word "to" is optional here. Often it will be omitted in this sentence.

You would use "watching" for TV or movies or videos, but not for text. A column is an article in a newspaper by a columnist (regular contributor). So you could say "you're watching my weekly video", or something like that. The title also needs a question mark at the end.

If you go to any of the parks in China you will definitely see a lot of empty bottles of this kind on the tables near the small shops.

"empty this kind of bottles" sounds unnatural in English. It's also not clear what you mean by "this kind", since you haven't described the bottles. This would be OK if you are making a video, and in the video you are pointing to a bottle so the viewer sees what you mean. But in written text, if you haven't described the bottles before, maybe you could say "empty bottles of a certain kind".

Today we’re going to find out what it is, and whether it's delicious or disgusting. Let’s go!

After talking to a sales person I found out that this is a traditional Beijing food called “Fengmi suanniunai”. I would call it “Beijing honey yogurt. It has been produced in Beijing for over 100 years and all the locals know what it is and seem to love it. So today I will try it too and tell you what I think about it l.

The price is only 5 yuan if you drink it right away and 6 for take away. Do you know why? It's because the bottle is refundable. You get 1 yuan back if you return the bottle. That’s why we see so many bottles left on the tables. The locals prefer to drink it quickly and continue their promenade.

Let’s take a closer look at it. To tell you the truth, the packaging doesn’t give the impression that it’s professional. The bottle is covered with a piece of paper which is fixed only with a rubber band. As you see, we don’t need to open it.

"As you see" only makes sense if you are making a video and the viewer can see what you are describing.

You just pink it with a straw and it’s ready to drink. But I want to see how it looks like, so I will open it. It’s white and thick. Let’s try it. Wow! it’s delicious! I never expected that. It’s sweet and tastes like a yogurt.

Let’s take a closer look at the bottle. Here you can see a list of the ingredients, which I will leave for you below, but it looks pretty healthy. Also there is the date when it was produced. You can drink it within seven days of that date. If you don’t trust in this pack you can buy the plastic bottle which has more credibility.

Today I tried the traditional Beijing honey yogurt and I loved it. I hope you like it too. Thank you for watching. Have you ever tried it? Do you like this yogurt? Please leave your comments below. Let me know if you have a product you want me to try, and I'll tell you what I think about it.
