All the operations in this book can be replaced by native Python, and Pandas package is not needed. Finding feelings is very important.

Now we can pass a function in, whether it is to create div or iframe. In short, if this is the case, we can use getInstance to get their instance objects.

Water sources should be guaranteed and water should be exchanged for drainage and irrigation.
