In Chinese, 在 can function as the main verb meaning to be located at/in. So 家电在新居里 is a complete sentence meaning that the appliances are located in the new home.

Chinese does not normally use 是 for location. So:

• 家电在新居里。 = The appliances are in the new home.
• 家电是新居里。 = incorrect

Here, 在 means to be at / to be in / to be located at.

It is not just a preposition in this sentence; it is doing the job of the main verb. That is why the sentence can be complete without another verb.

So the basic pattern is:

noun + 在 + place

Example:

• 书在桌子上。 = The book is on the table.
• 家电在新居里。 = The appliances are in the new home.

They work together, but they do different jobs.

• 在 marks location or means to be located
• 里 is a location word meaning inside

So:

• 在新居里 = in the new home / inside the new home

You can think of it roughly as:

• 在 = at/in
• 里 = inside

In many cases, Chinese likes this kind of structure:

• 在 + place + 里/上/下/前/后

Examples:

• 在房间里 = in the room
• 在桌子上 = on the table
• 在学校里 = in the school

Yes, sometimes you can, and native speakers may say it in the right context. But 在新居里 sounds more complete and natural because 里 clearly marks inside the new home.

Compare:

• 家电在新居里。 = The appliances are in the new home.
• 家电在新居。 = possible, but less specific and less natural in many beginner-style contexts

So for learners, 在 + place + 里 is a very safe and natural pattern.

家电 is short for 家用电器, which means household electrical appliances or home appliances.

It usually refers to things like:

• refrigerators
• washing machines
• air conditioners
• TVs

So 家电 is a common everyday word for home appliances as a category.

Chinese nouns usually do not change form for singular and plural the way English nouns do.

So 家电 can mean:

• a home appliance
• home appliances
• household appliances in general

In this sentence, it most naturally feels collective, so in English it is often translated as home appliances or the appliances.

You learn the number from context, not from the noun ending.

新居 means new residence or new home. It is a little more formal or polished than 新家.

• 新家 = new home, very everyday
• 新居 = new residence/new home, a bit more formal, often seen in moving-house or housewarming contexts

So 新居 is absolutely normal, but it has a slightly more refined tone.

Not exactly. The meaning is close, but the grammar focus is different.

• 家电在新居里。 puts 家电 first and says where they are:
  The appliances are in the new home.

• 新居里有家电。 uses 有 and introduces the existence of appliances there:
  There are appliances in the new home.

This is an important difference in Chinese:

1. A 在 B = A is located in B
2. B 有 A = B has / there is A in B

Both can be correct, but they highlight different things.

The pattern is:

subject + 在 + place + location word

So here:

• 家电 = subject
• 在 = located at/in
• 新居 = new home
• 里 = inside

That gives:

家电 + 在 + 新居 + 里

This is a very common Chinese sentence pattern for location.

Yes. 里 and 里面 are both possible.

• 在新居里
• 在新居里面

Both mean in the new home.
里面 can sound slightly fuller, while 里 is shorter and very common.

For beginners, both are fine.

It can be correct, but it usually adds emphasis or contrast.

• 家电在新居里。 = neutral statement
• 家电是在新居里。 = The appliances are indeed in the new home / It is in the new home that the appliances are

So 是 is not normally needed for a simple location sentence. If you add it, the sentence often sounds more emphatic or contrastive.
