heavy rain

In summer I like the rain, cuz it can cool the weather down. This week it rains has rained every day (two words, not one) in Shenzhen, so it's not so hot.
But there are also some problems, for example it's inconvenient to go out.

Heavy Rain

I like it when it rains in summer, because it can cool the temperature (In summer I like rain, cuz it can cool the weather down). This week it rained (rains) everyday in Shenzhen, so now it's not so hot. But there are also some problems, for example, it is less convenient (inconvenient) to go out.

Hi, Karen. We would put the title in initial capitals. Cuz is text slang so you cannot use that (you will be failed in an interview or English exam) - so use 'because'. This week refers to the past few days so you have to use 'rained' which is past tense of to rain.
