Hi Cecil
My neighbour has placed a cactus plant in their front door entrance which also somehow faces our house. Hope you could advise whether this will affect us. I attach herewith the photos for your reference.
Thanks.

These are some considerations:
1. Fortunately, for now, the cactus is just a "stump" and does not seem to have torns (correct me if I am wrong). This is a plus point.
1.1 If the cactus is tall and lots of "branches" then, it is a concern.
2. Under the Five elements concept, fire or something RED can be used against it: Not possible to move your plant to the same side of the cactus? (If so, understand as the area "belongs" to your neighbour" or your main door is in the way should you place it to the right of the main door.
3. For now, just monitor the situation i.e. hopefully the cactus does not grow tall with lots of branches.

Further to what I had mentioned;

There are two other alternatives:

1. If one wants to apply "stealth" or stealth mode, is the use of highly reflective grille gates e.g. chrome or a reflective mirror on the gate.
2. The other is the traditional method of placing a convex mirror above the door.

Hi Cecil, thanks for your advice. At which location of the door is appropriate - right top or left top or?

If one does not want to place one of those conVEX mirrors; then this (stealth-mode) is a possibility:-

Please note that the "mirror" need not be exactly facing the cactus. So long as it shares the same concept of a convex mirror above the door or as mentioned in the first link is fine or OK.

Hi Master, 

What if its your downstairs direct hdb owner that placed a huge catus. Does it affect us on the level above? Coz after i purchased the flat we have been habing quarrels at home and also sprained a leg. 

Most likely it is a coincidence. And unlikely a threat:

Given that what’s separating both floors is a concrete level. And even if the cactus is huge, it is not some sort of exploding grenade.

There must be other imbalances within your home...
