Never Tired of Teasing

While Salem was learning the Chinese language, Zhang Zian was curious about the semi-transparent miniature whirlwinds that he saw between the dunes. How did they form? Why didn't they dissipate after a while?

Was it due to the unique geographical landscape? When the wind blew through the honeycomb sand dunes, it changed direction because of the shape of the sand dunes. Might this be similar to how water formed a vortex after flowing through a reef?

In order to learn the authentic Chinese language, Salem diligently helped Zhang Zian by carrying the drone suitcase. Wherever Zhang Zian went, he followed and tried to learn from him.

The strange phrases that Zhang Zian said made him curious. He had never heard them before while interacting with Chinese tourists. 

"Zhang Zian, can you say it again? I didn't hear it clearly," he begged.

"What are you looking at?" Zhang Zian repeated.

"You... stinky prawn?" Salem tried to imitate the pronunciation.
