If you cannot find spring onions, then use scallions or leeks instead. Tofu can be found in China stores, or you can try to make yourself at home. It's not as difficult as you have thought.

1. Clean the spring onions and cut them into chunks at an angle. Coarsely shred the carrot. Slice the tofu into smaller pieces, about 5x3 cm. Sprinkle salt over and let marinate for 1 hour.
   
2. Heat up some oil in a skillet until hot. Add in tofu slices and fry until crispy and golden brown on both sides. Drain. In another skillet, add in chilli oil and minced garlic. Stir-fry until aromatic, then add in carrots and white part of the spring onions. Stir-fry briefly, return the fried tofu to the skillet, and drizzle in maggi sauce, rice wine, water and chicken bouillon. When it comes to a boil add the greens. Stir to combine and dish off.
