　　The first time I climbed this bridge, I just climbed here, my feet will be soft.

Especially in summer, because it is a hot place, the subtropical climate is very humid, and the sun grows moss. The rainy season is very humid, and people will slip on their feet when they go up.

Because it hasn't rained in the past two days and the fog is small, we can climb (safely).

In the usual rainy season, we have to watch the weather forecast, and we dare to climb by looking at the weather conditions of the next day (no rain).

　　[Explanation] In accordance with the maintenance requirements, the work area shall inspect the bridge and tunnel in charge once a month.

Many people have stayed here for many years to ensure the normal operation of the Yunnan-Vietnam Railway for a century.
