If you want to place heavy decorations such as ceramic ornaments, everlasting flower bouquets, etc., the method of inserting them diagonally with adhesive tape won't work well, so you can try the straw support method. Cut a piece of thick straw that matches the height of the decoration, use hot melt glue to stick the decoration on the top of the straw, pay attention to the glue point to avoid touching the cake, and then insert it vertically into the centre of the cake, using the friction force of the wall of the pipe to fix it firmly.
The top tier of multi-tier cakes often wobbles due to the unstable centre of gravity. In this case, you can use laminating pegs or long bamboo skewers to vertically penetrate the tray and the cake at the edge of the tray, tie the decoration to the top or fix it with clips, and then use buttercream or fruits to cover the fixing point cleverly. If you need to quickly and temporarily fix small, light metal jewellery or sugar tags, melt a small amount of chocolate or sugar paste, press the decoration on while it is still hot and refrigerate for 5 minutes to set.
In addition to these methods, it is possible to insert several decorations in a scattered manner so as to form a stable triangle. Be sure to take care when doing this to avoid hot melt glue and tape coming into direct contact with edible parts, put sequins or small flags on the end of the bamboo stick to remind you that it's 'not edible', and gently shake the cake when you're done decorating it to test the load-bearing capacity ahead of time.
