Feed Pig

In your writing, you talked about multiple pigs and piglets. I won't correct this, though I would recommend making it plural in these circumstances.

Catch Insect

Same case as before. Recommend for it to be made plural.

The main part of it is a thin and long wooden stick and we attach a bucket to its lower end.

Or you could use:
"The main part of it is a thin and long wooden stick and a bucket is attached to its lower end."
Or
"The main part of it is a thin and long wooden stick and attached to its lower end, is a bucket."

We hold the stick down to make the bucket full of water first and then lift the bucket out of the well.

"Down" describes how you hold the stick to get the water. You don't just hold a stick to make a bucket full of water, unless you do? If so, then teach me your ways.

Every family has a farmyard manure pond in a corner of their front yard, and after a certain time they take the stuff inside the pond out and dry it under the sun.

The comma (,) entails that there is a pause in the sentence. This sentence can be said in one breath, though it is better to use a comma to prevent a run-on sentence. If you have any questions about this, you can ask.

Afterwards, people knock it into small pieces and it wais done to be used as farmyard manure.

"Knock" is not past tense. This means that "was" has to become "is".

We only have a manpowered cart and we need to transport fertilizer to the field many times.

Farm Wwork and Housework in the Old TimePast

The fFarm work and housework I did in the old days.

It’s inevitable that I have to help my parents to do some farm work and housework, although it is not too much.

Feeding Pigs

In order to increase our family’s economic income, my father prefers to raise sows, which can gives birth to piglets.

We raise the piglets until they are a little older and sell them.

ThePig food for pigs is made of wheat bran and small cubes of sweet potatoes.

When we make pig food, we first pour the food materialingredients into a red pottery tub first and then. Then, we pour boiling water in it and stir it to make it like porridge.

WhenAfter it cools down, we take it to the pigsty to feed the pigs.

Cutting Grass

Familyies in the countryside often feed livestock, such as cattle, goats, and ducks, and t. These livestock eat grass.

ManyThe wild grass in the farmland affects the growth of crops.

We often take a basket and a sickle going to the field to cut those wild grass and take it home to feed the livestock.

Catching Insects

We plant cotton every year and t. The cotton is easily infested with insects.

I go with my mom carrying a small glass bottle to the cotton field with my mom to catch insects and put insectsthem into the bottle.

Before the Chinese New Year, a tradition of villagers is tothere is a village tradition of frying mung bean balls.

The first step of it is to grind the mung beans, but we don’t have any modern devices except a millstone.

Transporting Farmyard Manure

Every family has a farmyard manure pond in a corner of their front yard and after a certain time, they will take the stuff inside the pond out and dry it under the sun.

Afterwards, people knocbreak it into small pieces and it was done to be used as farmyard manure.

We only have a human-powered cart and, so we need to transport fertilizer to the field many times.

There is still a lot of other farm work and housework.
