Let's do the math. Trucks are usually classified according to their load:
Heavy trucks: the load capacity is more than 8 tons;
Medium-sized trucks: the load capacity is 4-8 tons;
Light truck: the load capacity is 1-3.5 tons;
Minitruck; The load capacity is below 1 ton;
Sister can't be so strict, so let's calculate it according to the median of medium-sized trucks, 6 tons.
A bottle of salted soda (Yanzhong brand) is 600ML, calculated according to 0.6 kg, 6 tons /0.6 kg = 10000 bottles.
1.7 yuan per bottle, which is 17000 yuan. Two trucks, 34 thousand. Sister is not expensive!
