Border county thrives on spring birding tours

Bird guide He Zhengzhong made it very clear to his son and daughter that they should not use a slingshot to hit birds, though that was his favorite childhood pastime.

"Absolutely not now," he said. "Especially when the kids have summer or winter breaks. No one can play with a slingshot. The birds are too precious.

"If you hit one bird in the spring, you will lose a whole nest of them when autumn comes," he added, citing an old saying.
