回复：急请教，水龙头一打开就发出恐怖的声音！

It is called "Water Hammer"

Try this:
Step one: shut off the water from the street.
Step two: turn on all faucet in the house let water run out
Step three: turn on the water from the street.
Step four: turn off the water in the house.
Still happen, the 厨房的水龙头 is about to leak and need to be fixed
