How to install the kitchen sink hose?

The materials prepared are as follows: buy a new sink drain pipe, wrench, triangle valve, raw material belt, and hose faucet.
If the triangle valve at home is rusted out, replace the triangle valve first.
Use a wrench to unscrew the old valve. The new valve is best made of copper. This is more durable. You need to wrap a certain number of raw material tape around the thread. You can control how many times you want to wrap. The ultimate goal is to wrap it without water leakage. Then screw on the new copper triangle valve, there are two in total, one for the hot water pipe and the other for the cold water pipe.

Now start to connect the kitchen-sinks-universal-hose and faucet correctly. My faucet is not broken, so I just use this old one.
The steps should be:
1. Put the casing of the faucet directly on the 2 hoses;
2. Then the hose passes through the socket of the faucet from below,
3. Insert the copper connector of the hose into the faucet, and tighten both of them. Be careful when screwing, don't use brute force, use clever force. But don't break as shown in the figure below.
After these steps are completed, the last 2 steps are left,
One is to fix the faucet.
One is to connect the hot and cold water pipes at the lower triangle valve respectively.
Be careful when screwing the faucet hose into the faucet and never use brute force.
Change the triangle valve first, and then when screwing the faucet hose into the faucet, pay attention to the sleeve first, because the sleeve will be used to fix the faucet when it is underneath; then go out from the faucet socket, and then tighten the faucet. This step must not be reversed, otherwise it will be very painful.
It is advisable to wrap the raw material belt so that it does not dew.
