Hello cCat.

IF their name is Cat, you need to give the name a capital letter.

I can understand your Mandarin very well, although your Mandarin is not that good honestly.

This is fine, although being abrupt can come across a bit rude in a lot of English speaking cultures.

If this is a friend you are speaking to, you could try this instead:
''I can understand your Mandarin very well, although your Mandarin is still quite basic!''

You could also add if you like:
''Learning Mandarin takes a lot of time, you have made a good start''

Yes, I did visit Macao at that time, but I was not as excited as when I visitinged Hong Kong.

I was even disappointed because Macao’s look was much less beautiful than Hong Kong visually.

In some areas it looked like Hefei, the capital of Anhui, in the eighties in some areas.

I visited the Macao ruins of ST, Macau New Lisboa Casino and Venetian Macao-Resort-Hotel, but I didn’t gamble.

Hello c, Cat.

I remember I paidpaying about 2,600 rmbRMB for that video camera and it, which was brand wased 禄来 (rulei?).

Using "remember paying" is more fluid. "RMB" should be in uppercase as it's an abbreviation.

), butHowever, I can’'t getfind any information about it on the internet.

Shorter sentences are usually better for the sake of clarity so I split the sentence into two.

I can understand your Mandarin veryquite well, aleven though your Mandarin is not that good honestlyit's not perfect.

The original sentence can sound too direct, and even offensive. This is less direct and has a different tone.

But nodon't worriesy, as a native Chinese spersonaker, I can understand anyone who can speak even just a littleknows even a bit of Chinese.

The original can work just as fine, but this one is shorter and has better flow, I think.

The international luxury brands I heard from the tour guide mentioned that time wereincluded LV, Gucci, Prada, Fendi, Dior, Cartier, Burberry, Rolex, and so onothers.

The new sentence sounds smoother and makes the "hearing" aspect more intentional rather than passive.

Yes, I did visit Macao at that time, but I was non't as excited as I was about visiting Hong Kong.

More concise, and fixed the grammar of the second clause.

I was evenquite disappointed because Macao’s look wased much less beautiful than Hong Kong.

"Even" sounds like you're trying to say something really shocking given the context of your previous sentences, but none of the previous sentences hinted at this idea. Example: "Oh, I didn't actually like Macao. I was even quite disappointed." I also fixed the rest of the sentence to make it sound more natural.

It looked liken some areas, it reminded me of Hefei, the capital of Anhui, back in the eighties in some areas.

Rearranged for better clarity.

I visited the Macao ruins of ST, the Macau New Lisboa Casino, and the Venetian Macao-Resort-Hotel, but I didn’'t gamble.

I don’'t like gambling, and I don’'t think I am capable of gamblingbelieve I'm suited for it.

The original is fine with corrections (I don't like gambling and I don't think I'm capable of it.) but this one sounds more fluent.

I remember I paid about 2,600 rmbRMB for that video camera and its brand was. It was made by 禄来 (rulei?

It was correct, just the sentence was a little long.

Two waitresses at the entrance bowed to me and said “wWelcome to Fendi.” That was the only English sentence that I could understand back then.
