I have purchased a Raspberry pi 4 with 4GB RAM for my dad as a desktop replacement. He only uses it to login to the bank, check news and look for deal.
Here are some commands I used to update the Raspberry OS.
sudo apt update
sudo apt full-upgrade
Use commands below to check temp of the board and CPU
sudo vcgencmd measure_temp
sudo vcgencmd measure_volts
To read Chinese in the browser, run the command below to install the fonts.
sudo apt-get install fonts-arphic-uming
