As you know it is really a controversial topic, isn't it?

Normally speaking, an appreciated currency will make domestic product harder to compete in the global world, because of increased product or service price.

Our product is very competitive because of depreciated currency.
That is the origin of our soaring GDP and steady social status (good employment rate).
U.S. blames our mandatory exchange rate policy, they even threaten to punish us for that.

On the other hand, depreciated  currency makes our life less colorful.
We will find it is really difficult for us to consume foreign product or service, unaffordable.

In summary, there is no right or wrong answer for this topic.
Totally depends on your standing point.
Let me know if you need further discussion about it.
Thanks.

thank you so much
