To be honest, I don't like the cold weather.

Country names are proper noun so they should start with the capital letter.

I've lived in bBali for three months.

The first thing is athat the people are polite.

I've never seen such a polite people like hebefore.

When I see baliaw Bali the first time, I thought I'm on thein heaven.

I couldn't believe how gGod can create all this beauty.

God begins with the capital letter.

Today is my first day here btw.

Thank you guys, and I wish you luck

HereIt is winter here now, so the weather is getting colder by the day.

It is more natural to have "here" in the middle of the sentence, rather than at the beginning.

I was planning to go to a warm country such as bali.

I've lived in bali for three months.

"I've lived in Bali" means that you are living in Bali right now. "I lived in Bali" means that you were living there in the past, but you aren't living there anymore.

I liked so muchreally enjoyed this experience in my life.

"I really enjoyed" sounds a little more natural. "So much" usually comes at the end of sentences.

The first thing is athat the people are polite.

When you are talking about a phrase with a verb ("the people are polite", where the verb is "are"), you want to use the word "that" before the phrase.

You can also say "The first thing is the polite people". Since the phrase "polite people" does not have a verb, you don't need to use "that".

I've never seen such a polite people like the ones here.

"The ones" is referring to the polite people. You can also replace it with "people" again ("I've never seen such polite people like the people here"), but it is a little repetitive.

The second thing is that the nature is wonderful.

This is the same as the sentence about polite people. "Nature is wonderful" has a verb ("is"), so you need "that" in the sentence.

When I seeaw bali for the first time, I thought I'm on the was in heaven.

"Saw" should replace "see" because it is something you did in the past.
"In" is usually used when talking about places, such as heaven.

I couldn't believe how god canreated/could create all this beauty.

You can use "created" since nature's beauty was created in the past, or you can use "could create" which shows the ability to create this beauty more naturally.

Today is my first day here btw.

Welcome!

Thank you guys, and I wish you luck

Sometimes you can write sentences without using "I", but it is better to have it here.

Here iIt's winter now,here now and the weather is getting cold by theer day by day.

It's important to use the comparative "colder" here, as you compare each day to the one before.

To be hHonestly, I don't like the cold weather.

Nothing wrong grammatically with your sentence. This is just more natural.

I 've always planningwanted to go to a warm country such a b, like Bali.

Again, nothing really wrong here, except for the missing comma. This just flows more naturally.

I likoved so much this experience in my lifthe experience.

The first thing is aFirst, the people are polite.

I've never seenmet such a polite people likas I have here.

The second thing isSecond, the nature is wonderbeautiful.

Nothing really wrong, again.

When I see baliaw Bali for the first time, I thought I'm on the h was in Heaven.

1. Use the past tense when speaking of experiences that happened in the past. On the other hand, you can say "When I first saw Bali, I think, 'I'm in Heaven.'" The difference is that the first sentence is what you felt at that time ("I thought I was in Heaven.") The second setence is a quote of what you thought at the time ("I thought, 'I'm in Heaven.'")
2. Generally, we say "in" when we're inside something, like a place. "I'm in the forest. I'm in the desert." But, we say "on" when we're on top of it "on the roof," "on a train." This is a little confusing, since we're "inside a train" but we say "on the train." English is weird.

I couldn't believe how god can created all this beauty.

Seeing it made me happy.¶
or¶
I was so happy to see ithis.

I hope that we willcan help each other.

Nothing really wrong with the sentence.

Thank you guys, and I wish you luck.
