I learning other languages for connecting with two different things.

Maybe the people have different nationalities or share different cultures, thinkings, lifes and information. It really makes me feel excited!

And following grown ages, I'd like to use language skills to get a better job, but it’s just  my own slight thinking, because I don't know how to start it!

I don't know learning languages whether could help you be smarter or not.

But I'm sure that your mother tongue will be better then you were, especially you are doing language exchange! :)

買汽車

Buying a car exercise:
■請問，先生，您要買汽車嗎?
□對啊，我的汽車太舊了。我可以看看這三輛汽車嗎?
■你可以，你喜歡哪輛車?這輛汽車看起來好看，對不對?
□還好。這輛車賣多少錢?
■這輛車賣兩萬塊錢。
□真的嗎?它太貴了。那兩車比較便宜嗎?
■那輛車比較便宜。它也比較大但是比較舊。

I haven't finished the exercise but have a couple of questions:

Is there a rule to follow of when to use 輛汽車 and when I can just use 輛車?
比較 is a new word for me, not sure if I am using it correctly.

多謝
Thank you

At the first, 輛 is the measure word in Chinese.
You should use Pronouns or Articles to complete a phrase:
那輛汽車、那輛車或者一輛汽車、一輛車，這才是一個完整的詞。

車：All kind of vehicles moving by wheels.
If you keep learning Chinese you will see 腳踏車(bike), 汽車(car), 機車(scooter), 卡車(truck) …etc. soon. And then you will find out these words all with the Chinese character 車 no matter what we change the adjective before it.
So 車 is a easy way what we call these vehicles moved by wheels sometimes.

Is there a rule to follow of when to use 輛汽車 and when I can just use 輛車?
For example:
1.
A：那(That)輛車是誰的(who’s)? A just used shortened form to ask B. Maybe there are bikes, cars, scooters parked.
B：哪一輛車？(Which one? )
A：那輛汽車！A used the adjective to make B know it more clearly.
B：噢！我的。

2.
In your exercise situation, because we all know only one kind of vehicle over there, car, we just use easy way to say it not have to use formal way(汽車) to describe it.

Finally, keep up your good work! ;)

I think I’m also judging a person who judging person by the appearance is unwise now .
What person doing is wise so-called?

We are the human being and judge everything… We can't top them, it’s the instinct from birth!
No matter how people judge us, the most important thing is how we face and solve the judgments.

So I would like to tell the people who have been attacked by critics. We can’t make all the people in this world to like us and you are that unique one in this world and only one to know yourself well.

Finally, I thank the people who make people feels considerate and with empathy!
