I wanted to know this also.
Those weight supporting structure or beam, they cannot be hacked.
But what I want to know is, can hole drilling even allowed on those beam?

There are few ways to identify between bearing wall and partition wall.
Saw one article in Taobao app yesterday night but managed to remembered three.
1.If you have floor plan, usually those wall with black colouring is the bearing wall.
2. Knock the wall, bearing wall will sound more rigid than partition wall.
3. Bearing wall (around 24cm) is generally thicker than partition wall (10cm to 15cm).
