Any mistake, please ?

Hello,

Could you please, check if there is any mistake in the following words (for some I give my own definitions to see if the words match with them):

- sustenance farming (when you have your small kitchen garden, i.g. for your own sustenance);

- to crop or pick (up) green fruits in the trees;

- homemade food (food that you prepare at home, usually simple and tasty);

- pipe cars (in regions in which there is a severe draught for example, people can buy water from pipe cars. It often happens in regions of underdeveloped countries);

- a pig and chicken breeding ( when you breed pig, chicken and other animals usually for your sustenance. for instance);

- a permanent job/employment/work;

- saturated market (when there are too many doctors, lawyers, architects, teachers,.. in the job market);

- tinned lunch (i.g. when you don't want to eat in any restaurant or you are without much time so you bring food from your house into a metal pan with a lid in a meal frame for carrying food; so we may say you have a tinned lunch);

- What do we call those very poor houses that can be found in slums (very commom in underdeveloped countries ?);

- street peddlar (the person that for choice or lack of job opportunity starts to sell several things in a stall on the streets);

- What do we call the act of washing clothes to make/earn a living ?

I do appreciate your kind help,

Sebastian
